This Week in Television History: September 2024 PART III

      

September 16, 1949

Edward James Begley, Jr. was born. 

The actor and environmentalist. Begley is perhaps best known for his role as Dr. Mark Craig's intern, Dr. Victor Ehrlich on the television series St. Elsewhere, for which he received six consecutive Emmy Award nominations. He also had a reality show about green living called Living With Ed on with his wife, actress Rachelle Carson. Commenting in 2006 on the appeal of the show, Begley said:

"In the format of the show, everyone who watches—even people who have never thought about living a low-impact, environmentally conscious life—will be able to relate. They’ll come away with a raised awareness, but they’ll also enjoy seeing the differences between the Rachelle and me." 


September 16, 1949

Warner. Bros. introduces the Road Runner in the cartoon short "Fast and Furry-ous." Like the sounds of countless other Warner Bros. cartoon characters, the Road Runner's cheerful "beep, beep!" was provided by Mel Blanc.


September 16, 1964

Shindig! premiered on ABC. 
The show was hosted by Jimmy O'Neill, a disc jockey in Los Angeles at the time who also created the show along with his wife Sharon Sheeley and production executive Art Stolnitz. The original pilot was rejected by ABC and David Sontag, then Executive Producer of ABC, redeveloped and completely redesigned the show. A new pilot with a new cast of artists was shot starring Sam Cooke, The Everly Brothers, The Wellingtons, The Righteous Brothers, Bobby Sherman and Alan Sues. That pilot aired as the premiere episode.

September 16, 1984

The first episode of Miami Vice aired on NBC. 

The crime drama series created by Anthony Yerkovich and was produced by Michael Mann for NBC. The series starred Don Johnson as James "Sonny" Crockett and Philip Michael Thomas as Ricardo "Rico" Tubbs, two Metro-Dade Police Department detectives working undercover in Miami. The series ran for five seasons on NBC from 1984–1989. The USA Network later began airing reruns the next year, in 1990, and actually broadcast an originally unaired episode during its syndication run of the series on January 25, 1990.

Unlike standard police procedurals, the show drew heavily upon 1980s new wave culture and music. The show became noted for its heavy integration of music and visual effects to tell a story. It is recognized as one of the most influential television series of all time. People magazine stated that Miami Vice "was the first show to look really new and different since color TV was invented". Seasons two to five were aired in stereo. Episodes of the show have become popular in syndication since its cancellation both in the U.S. and in several foreign markets, a testament to the show's ongoing appeal.

Michael Mann directed a film adaptation of the television series, which was released on July 28, 2006.


September 17, 1964

Bewitched first aired. 

The fantasy situation comedy originally broadcast for eight seasons on ABC from 1964 to 1972. It was created by Sol Saks under executive director Harry Ackerman, and stars Elizabeth Montgomery, Dick York (1964–1969), Dick Sargent (1969–1972), Agnes Moorehead, and David White. The show is about a witch who marries an ordinary mortal man and tries to lead the life of a typical suburban housewife. Bewitched enjoyed great popularity, finishing as the number two show in America during its debut season, and becoming the longest-running supernatural-themed sitcom of the 1960s–1970s. The show continues to be seen throughout the world in syndication and on recorded media.


September 18, 1964

The Addams Family first aired. 

Based on the characters in Charles Addams' New Yorker cartoons. The 30-minute series was shot in black-and-white and aired for two seasons on ABC. It is often compared to its CBS rival, The Munsters, which ran for the same two seasons and achieved somewhat higher Nielsen ratings. The show is the first adaptation of the characters to feature The Addams Family Theme.

The Addams Family was originally produced by Filmways, Inc. at General Service Studios in Hollywood, California. Successor company MGM Television (via The Program Exchange for broadcast syndication and 20th Century Fox Home Entertainment for home video/DVD) now own the rights to the show.


September 19, 1964

Flipper first aired on NBC

Flipper, a bottlenose dolphin, is the companion animal of Porter Ricks, Chief Warden at fictional Coral Key Park and Marine Preserve in southern Florida, and his two young sons, Sandy and Bud. The show has been dubbed an "aquatic Lassie", and a considerable amount of juvenile merchandise inspired by the show was produced during its first-run.


September 20, 1984

The Cosby Show first aired. 

Bill Cosby starred in the show that focused on the Huxtable family, an upper middle-class African-American family living in Brooklyn, New York, at 10 Stigwood Avenue. The patriarch is Heathcliff "Cliff" Huxtable, an obstetrician, son of a prominent jazz trombonist. The matriarch is his wife, attorneyClair Huxtable née Hanks. They have five children, four daughters and one son: SondraDeniseTheodore (Theo for short), Vanessa and Rudy. Despite its comedic tone, the show sometimes involves serious subjects, such as Theo's experiences dealing with dyslexia, inspired by Cosby's son Ennis, who was also dyslexic. The show also deals with teenage pregnancy when Denise's friend, Veronica, played by Lela Rochon, becomes pregnant.

The show's theme music, "Kiss Me", was composed by Stu Gardner and Bill Cosby. Seven versions of this theme were used during the run of the series, making it one of the few television series to use multiple versions of the same theme song over the course of a series. For season four, the theme song music was performed by musician Bobby McFerrin. Due to legal complications regarding the background mural, the opening for season seven was replaced with the one from the previous season. The original season seven opening, with slight modifications, was also used in season eight.


September 21, 1999

HBO's live music show Reverb debuted with performances by Alanis Morissette and Everlast. 


September 22, 1964

The Man from U.N.C.L.E. first aired on NBC. 

It follows the exploits of two secret agents, played by Robert Vaughn and David McCallum, who work for a fictitious secret international espionage and law-enforcement agency called U.N.C.L.E. Originally co-creator Sam Rolfe wanted to leave the meaning of U.N.C.L.E. ambiguous so it could be viewed as either referring to "Uncle Sam" or the United Nations. Concerns by the MGM Legal department about possible New York law violations for using the abbreviation "U.N." for commercial purposes resulted in the producers clarifying that U.N.C.L.E. was an acronym for the United Network Command for Law and Enforcement. Each episode of the television show had an "acknowledgement" credit to the U.N.C.L.E. on the end titles.

 

September 22, 1964

Land of the Giants first aired


September 22, 1979

ABC began airing the first episode of Hart to Hart

The premise of the show is summed up in its famous opening lines, spoken by the character Max: "This is my boss: Jonathan Hart, a self-made millionaire. He’s quite a guy. This is Mrs. H -- she’s gorgeous. She’s one lady who knows how to take care of herself. By the way, my name is Max. I take care of both of them -- which ain’t easy; ‘cause when they met, it was murder."

Jonathan Hart (Robert Wagner) was a self-made millionaire and the CEO of Hart Industries, a Los Angeles-based global electronics conglomerate. His wife Jennifer (Stefanie Powers) was a beautiful freelance journalist. Living the jetset lifestyle, the glamorous couple spent their free time as amateur detectives and in every episode they found themselves involved in cases of smuggling, theft, international espionage, or most commonly, murder. At their opulent California estate, they were assisted by Max (Lionel Stander), their loyal, gravelly-voiced butlercook, and chauffeur who also helped with their "cases." The Harts' beloved pet dog was a Löwchencalled "Freeway," so named because he was a stray that they found wandering on the freeway. The Harts own a Mercedes-Benz 300 TD diesel wagon, a dark green Rolls Royce Corniche convertible (replacing the Series III Bentley custom cabriolet in the first season), and a yellow Mercedes-Benz SL roadster (1979 450 SL, replaced by a 1981 380 SL) with personalized California vanity plates 3 HARTs, 2 HARTs, and 1 HART respectively. The trailer also shows a side view of Jonathan Hart driving a red Dino 246 GTS. They also own a Grumman Gulfstream II private jet, which is featured at the start of each episode. Max describes the couple as well as himself at the start of each episode.

September 22, 1989

NBC began airing the series Baywatch. 

Baywatch is an American action drama series about the Los Angeles County Lifeguards who patrol the beaches of Los Angeles County, California, starring David Hasselhoff. The show was canceled after its first season on NBC, but survived and later became one of the most watched television shows in the world. The show ran in its original title and format from 1989 to 1999, except for the 1990–1991 season, during which it was not in production. From 1999 to 2001, with a setting change and large cast overhaul, it was known as Baywatch Hawaii.

Baywatch premiered on NBC in 1989, but was canceled after only one season when it placed 73rd out of 103 shows in the seasonal ratings and also because the studio, GTG, went out of business. Feeling the series still had potential, Hasselhoff along with creators and executive producers Michael Berk, Douglas Schwartz and Greg Bonann revived it for the first-run syndication market in 1991. Hasselhoff was given the title of executive producer for his work on bringing the show back. The series was hugely successful, especially internationally. The show led to a spin-offBaywatch Nights, and a reunion movie, Baywatch: Hawaiian Wedding.

In 1999, with production costs rising in Los Angeles, and the syndication market shrinking, the plan was to move the show to Australia and launch Baywatch Down Under. A pilot was filmed but the series was stopped when residents of Avalon put forth strong objections, including potential damage to a fragile ecosystem. Pittwater Council permanently barred all future filming. This pilot finally aired as a two-part episode of Baywatch.

As an alternative to AustraliaHawaii offered the producers large financial incentives to move the show to the islands instead, and in Season 10, Baywatch Hawaii was launched.

Baywatch filmed for two seasons in Hawaii, from 1999 until 2001. The proposal to relocate Baywatch to Hawaii rather than Australia was initiated by April Masini in a telephone call to executive producer Greg Bonann. The deal to provide the incentives necessary to secure the series was presented to Governor Ben Cayetano by Al Masini and April Masini; Tony Vericella, president of the Hawaii Visitors and Convention Bureau; and Cayetano's executive assistant, Joe Blanco. The agreement required the production to change its name from Baywatch to Baywatch Hawaii, hire local leads, and film in the state for at least two years, guaranteeing 44 episodes, each at a cost of about $870,000, 60% of which was to be spent in Hawaii.


 September 22, 1994

Friends debuts, debuts on NBC. 

The show, which featured a group of relatively unknown actors, went on to become a huge hit and air for 10 seasons. It also propelled the cast--Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer--to varying degrees of stardom and success in Hollywood.

Of the six main Friends cast members, Jennifer Aniston emerged as arguably the most famous. Aniston played the fashion-loving Rachel Green, who, when the show began, worked as a waitress at Central Perk, a coffee shop that served as a gathering spot for the friends. The actress’s blonde, layered hairstyle during the first season became known as “The Rachel” and was copied by women around the globe. Off-screen, Aniston, whose film credits include The Good Girl (2002), Bruce Almighty (2003), Rumor Has It (2005) and The Break-Up (2006), became a tabloid-media fixture for her relationship with the actor Brad Pitt. The couple married in a lavish ceremony in Malibu, California, in 2000 and announced their separation in early 2005 amid soon-to-be-confirmed rumors of Pitt’s involvement with the actress Angelina Jolie.

Courteney Cox, the best known of the cast members when Friends debuted, played Monica Geller, a neurotic, hyper-organized chef. The actress, who first gained notice when she appeared in the 1984 Bruce Springsteen video “Dancing in the Dark,” acted in the popular sitcom Family Ties and co-starred opposite Jim Carrey in 1994’s hit comedy Ace Ventura, Pet Detective (1994). She was later featured in the successful Scream movies and the TV series Dirt. Since 1999, she has been married to the actor David Arquette and goes by the professional name Courtney Cox Arquette. The third female Friends cast member, Lisa Kudrow, portrayed the wacky masseuse-musician Phoebe Buffay. Kudrow’s film credits include Romy and Michelle’s High School Reunion (1997), The Opposite of Sex (1998), Analyze This (1999) and its sequel Analyze That (2002) and P.S. I Love You (2007). In 2005, she headlined the well-reviewed but short-lived HBO comedy series The Comeback. 

The male Friends included Matt LeBlanc as Joey Tribbiani, a handsome but dim-witted struggling actor. From 2004 to 2006, LeBlanc starred in the spin-off TV series Joey. 

David Schwimmer played Ross Geller, a sensitive paleontologist and Monica’s older brother. One of the main storylines on Friends was Ross’s on-again, off-again relationship with Aniston’s Rachel. Schwimmer’s other acting credits include the 2001 TV mini-series Band of Brothers. Rounding out the Friends cast was Matthew Perry, who played the wisecracking businessman Chandler Bing. Perry’s film credits include Fools Rush In (1997), The Whole Nine Yards (2000) and The Whole Ten Yards (2004); more recently, he co-starred on the short-lived NBC comedy-drama series Studio 60 on the Sunset Strip.


September 22, 2004

The Federal Communications Commission voted to fine CBS a record $550,000 for indecency related to the Super Bowl in which Janet Jackson's right breast was exposed. 

The FCC fined each of the 20 CBS-owned television stations the maximum penalty of $27,500. 

September 22, 2004

CBS News announced that a panel would investigate the 60 Minutes story that used forged documents to question U.S. President George W. Bush's National Guard Service. 

The segment was based on several alleged memos from Bush's days in the National Guard. The memos were called forged or fake by many document experts.

James Earl Jones on Sesame Street

 


James Earl Jones 
(1931-2024)

This is from Muppet WikiSesame Street Guest Stars

Early in his acting training, when studying at the American Theater Wing, one of Jones' teachers was Will Lee, who in 1969 would play Mr. Hooper on Sesame Street. Jones is considered by Sesame Workshop to be the first celebrity guest on Sesame Street, since inserts of the actor reciting the alphabet and counting numbers appeared in the unbroadcast test pilots and heavily influenced the show's pedagogical models. These inserts were later included in first season episodes, beginning with episode 0002. However, Jones didn't originally think the show would last and thought the Muppets were the problem; he told Matt Robinson that "this Muppet business has got to go, kids will be terrified."

In 1978, Jones appeared on Sesame Street in Episode 1148 as a movie star who visits Hooper's Store in search of the perfect egg cream. In the story, Mr. Hooper slowly recognizes him as a famous movie star, "I've seen almost every picture you've made!" (As a big fan, Mr. Hooper makes no mention of Jones's segments from Sesame Street’s early years where the cast would sometimes transition to his recitation of the alphabet by name. One of which, in Episode 0077, includes Mr. Hooper so furious over the misplacement of his glasses that he can't even think of the alphabet. Gordon urges him to watch James Earl Jones to help.)

Jones hosted the 10th anniversary Sesame Street special, titled A Walking Tour of Sesame Street in 1979. 

He returned to Sesame Street in 2004, taping a "My Favorite Sesame Street Moments" intro for Season 35.

In "Wuntafordy," an animated Sesame segment singing the numbers "1 to 40" a cappella-style by The Lemmings, Jones contributed the spoken voice saying "30."

Jones also performed the voice of the Mountain King in the Creature Shop-effects TV-movie Merlin.

The actor contributed a "Chilean Sea Bass" recipe for Miss Piggy's 1996 cookbook, In the Kitchen with Miss Piggy.

The James Earl Jones Factor

CTW Board of Advisors chairman Gerald S. Lesser and other researchers paid particularly close attention to James Earl Jones' appearance, in terms of children's response and the effectiveness of his alphabet recitation. Lesser described the basic performance as follows:

Mr. Jones' recitation of the alphabet takes a full minute and a half. He stares compellingly at the camera. At the time the sequence was made, his head was shaved for his role of Jack Johnson in The Great White Hope, and it gleams in the close-up. His immense hollow voice booms the letter names ominously. His lip movements are so exaggerated that they can easily be read without the sounds.<ref>Lesser, Gerald S. Children and Television: Lessons from Sesame Street. 1974. p. 120-121.

During the recitation, each letter appeared briefly near the actor's head prior to its being named, remains for the recitation and then disappears, and a pause in both Jones' speech and the visuals occurs before the next letter. The result of this particular staging prompted a particular positive response from viewers that producer Samuel Y. Gibbon, Jr. and research director Edward L. Palmer, as well as Dr. Lesser, termed "the James Earl Jones effect." The first time a child sees the performance, he responds to the invitation to say the alphabet along with the actor. Upon later viewings, the children would name the letter as soon as it appeared, but before it was named by Jones. Further repetition encouraged children to shout out the letter even before it appears. The "James Earl Jones effect" thus demonstrated to Sesame Street's producers and curriculum advisors the value of both repetition and anticipation, and supplied proof that Sesame Street could promote interactive learning as opposed to merely passive viewing.

Good Night Mr. Jones

This Week in Television History: September 2024 PART II

     

September 9, 1956

Elvis Presley sang "Don't Be Cruel" and "Hound Dog" on Ed Sullivan's show Toast of the Town. 

Presley scandalized audiences with his suggestive hip gyrations, and Sullivan swore he would never book the singer on his show. However, Presley's tremendous popularity and success on other shows changed Sullivan's mind. Although Elvis had appeared on a few other programs already, his appearance on Ed Sullivan's show made him a household name. 

September 13, 1969

Scooby-Doo, Where Are You! the first in a series of Scooby-Doo cartoons premiered on CBS. 

The original series, Scooby-Doo, Where Are You!, was created for Hanna-Barbera Productions by writers Joe Ruby and Ken Spears, CBS executive Fred Silverman, and character designer Iwao Takamoto. The show centers around four kids, whom were unofficially called "Mystery Inc." whose hobby was mystery solving. The basic premise remained unchanged through the many series of the franchise: criminal activities were covered up as faux supernatural events with red herrings and clues leading up to the eventual undoing. The meddlesome kids were Fred Jones is the stocky, straight-laced member; Daphne Blake, beautiful but danger-prone red-head; Velma Dinkley, the pudgy, bespectacled brains of the outfit; Norville "Shaggy" Rogers, the pencil-thin chow hound and the star of the show, the gangly, bow-legged Great Dane Scooby-Doo.

The original voice cast featured veteran voice actor Don Messick as Scooby-Doo, Top 40 radio DJ Casey Kasem as Shaggy, actor Frank Welker as Fred, actress Nicole Jaffe as Velma, and musician Indira Stefanianna Christopherson as Daphne.

September 13, 1974

The first episode of "Police Woman" aired on NBC. 

Based on an original screenplay by Lincoln C. Hilburn, the show revolves around Sgt. "Pepper" Anderson (Angie Dickinson), an undercover police officer working for the Criminal Conspiracy Unit of the Los Angeles Police Department. Sergeant William "Bill" Crowley (Earl Holliman) was her immediate superior, and Pete Royster (Charles Dierkop) and Joe Styles (Ed Bernard) were the other half of the undercover team that investigated everything from murders to rape and drug crimes. In many episodes, Pepper went undercover (as a prostitute, nurse, teacher, flight attendant, prison inmate, dancer, waitress, etc.) in order to get close enough to the suspects to gain valuable information that would lead to their arrest.


September 13, 1974

The first episode of "The Rockford Files" aired on NBC. 

The Rockford Files stared James Garner and aired on NBC between September 13, 1974, and January 10, 1980, and has remained in syndication to the present day. Garner portrays Los Angeles-based private investigator Jim Rockford with Noah Beery, Jr., in the supporting role of his father, a retired truck driver nicknamed "Rocky".

The show was created by Roy Huggins and Stephen J. Cannell. Huggins created the television show Maverick (1957–1962), which starred Garner, and he wanted to recapture that magic in a "modern day" detective setting. He teamed with Cannell, who had written for Jack Webb productions such as Adam-12 and Chase (1973–1974, NBC), to create The Rockford Files.

The show was credited as "A Public Arts/Roy Huggins Production" along with Universal Studios and in association with Cherokee Productions. Cherokee was owned by Garner, with partners Meta Rosenberg and Juanita Bartlett, who doubled as story editor during most of The Rockford Files run.

The series theme music by composers Mike Post and Pete Carpenter was released as a single and went to #10 on the Billboard Hot 100, remaining on the chart for 16 weeks. and won a Grammy Award for Best Instrumental Arrangement for 1975. In 2002, The Rockford Files was ranked #39 on TV Guide's 50 Greatest TV Shows of All Time

September 13, 2004

TV talk-show host Oprah Winfrey gives a brand-new Pontiac G-6 sedan, worth $28,500, to everyone in her studio audience: a total of 276 cars in all.) 

Oprah had told her producers to fill the crowd with people who “desperately needed” the cars, and when she announced the prize (by jumping up and down, waving a giant keyring and yelling “Everybody gets a car! Everybody gets a car!”), mayhem–crying, screaming, delirium, fainting–broke out all around her. It was, as one media expert told a reporter, “one of the great promotional stunts in the history of television.”

Alas, scandal wasn’t far behind. For one thing, the gift wasn’t really from Oprah at all. Pontiac had donated the cars, paying the hefty price tag out of its advertising budget, because the company hoped that that the giveaway would drum up some enthusiasm for its new G-6 line. (To this end, during the segment, Winfrey herself took a tour of a Pontiac plant, gushing over the cars’ satellite radios and fancy navigation systems.) The car company also paid the state sales tax on each of the automobiles it donated. However, that still left the new-car recipients with a large bill for their supposedly free vehicles: Federal and state income taxes added up to about $6,000 for most winners. Some people paid the taxes by taking out car loans; others traded their new Pontiacs for cheaper, less souped-up cars. “It’s not really a free car,” one winner said. “It’s more of a 75 percent-off car. Of course, that’s still not such a bad deal.”

Two months later, Oprah hosted another giveaway episode, this one for teachers from around the country. Their gifts were worth about $13,000 and included a $2,249 TV set, a $2,000 laptop, a $2,189 washer/dryer, sets of $38 champagne glasses and a $495 leather duffel bag. This time, the show’s producers had learned their lesson: they also gave each audience member a check for $2,500, which they hoped would cover the tax bill for all the loot. Unfortunately, it didn’t quite–most people in the audience owed the Internal Revenue Service between $4,500 and $6,000–but the PR gimmick worked: Oprah’s giveaways have earned some of the highest ratings in the program’s history.

September 14, 1984 

The MTV Awards are held for the first time. 

Bette Midler and Dan Ackroyd co-hosted the show honoring the best music videos from May 2, 1983, to May 2, 1984. The show was hosted by Dan Aykroyd and Bette Midler at the Radio City Music Hall in New York City.

Herbie Hancock was the night's biggest winner, taking home five awards, followed by Michael Jackson, who won three. The night's main award, though, went to The Cars for "You Might Think," making this the first of a very small number of times in which the winner of Video of the Year did not take home any other awards that night.

In terms of nominations, Hancock's "Rockit" and The Police's "Every Breath You Take" were the year's most nominated videos, with each receiving eight nominations apiece. Meanwhile, the most nominated artist of 1984 was Cyndi Lauper, who aside from winning the Best Female Video Moonman received nine nominations that year for two of her videos: six for "Girls Just Want to Have Fun" and three for "Time After Time."

Other major nominees that night included the aforementioned Michael Jackson and The Cars, both of whom received six nominations for their videos "Thriller" and "You Might Think," respectively; ZZ Top, who also received six nominations between their videos for "Legs," "Sharp Dressed Man," and "Gimme All Your Lovin';" and Billy Idol, who got five nominations for "Dancing with Myself" and "Eyes Without a Face." Lastly, David Bowie had four nominations for his "China Girl" and "Modern Love" videos, and he was also one of the night's honorees for the Video Vanguard award.
