At the end of the day... Trivia Quiz

Answer: Joan Rivers

No stranger to the talk show format, Joan Rivers had made a number of guest appearances on "The Tonight Show" (with both Jack Paar and Johnny Carson as hosts) and had served as the permanent guest host of that show for three years before getting the show on Fox.

After a good start, "The Late Show" foundered and both Rivers and her husband, show producer Edgar Rosenberg, were fired in May 1987. After her departure, the show had a number of guest hosts, including actress Suzanne Sommers and actor Richard Belzer, before Arsenio Hall did a 13-week stint as permanent host. Ross Shafer was the show's host when it went off the air in October 1988.

Answer: Frank Reynolds

Although Ted Koppel became the face of "Nightline" during its long and illustrious history, it was longtime correspondent and "ABC World News Tonight" anchor Frank Reynolds who started with the program in November, 1979. Reynolds stayed on until March, 1980, when Koppel, ABC's State Department correspondent at the time, took over. Koppel remained on "Nightline" until his retirement from ABC News in 2005. Reynolds died in 1983, only months after delivering his last newscast.

Answer: Linda Ellerbee and Lloyd Dobyns

All of the reporters listed here worked at NBC News at some point during their careers. But it was Linda Ellerbee and Lloyd Dobyns, who had worked together on another NBC News program, "Weekend", manning the anchor desks when "NBC News Overnight" debuted. Dobyns left the show in January, 1983, and fellow reporter Bill Schechner came on board for the rest of the show's run.

The signature signoff, "And so it goes...", was part of the title of Linda Ellerbee's 1986 autobiography.

Answer: Jonny Quest

Featuring the voices of James Urbaniak and Patrick Warburton, "The Venture Bros." made its debut on Adult Swim in February, 2003. The basic storyline of the show, involving the brothers Hank and Dean Venture, their super-scientist dad Dr. Thaddeus Venture, and bodyguard Brock Samson, parallels that of "Jonny Quest", a cartoon that revolved around the title character's globetrotting adventures with his super-scientist dad Dr. Benton Quest, his best friend Hadji, and his bodyguard Race Bannon. The Ventures did battle with a number of recurring villains during their run, including The Monarch and Phantom Limb.

Answer: Michael McDonald

The four cast members referenced in this question were with "MADtv" for at least eight seasons. But California native Michael McDonald was the only member of the cast to stick around for 10 seasons, joining the show in 1998 during the fourth season and leaving in 1998 after the 13th season.

He appeared in 239 episodes in that span - 41 more than the next most prolific cast member, Aries Spears. Before getting into the entertainment business, McDonald, who holds a business degree from Southern California, worked as a loan officer at a Los Angeles bank.

Answer: Palm Beach, Florida

Produced by Stephen J. Cannell, the man behind such hits as "The Rockford Files" and "The A Team", "Silk Stalkings" featured Rob Estes and Mitzi Kapture as police detectives who solve the crimes and who ultimately fall in love. Early in the show's run, actor and dancer Ben Vereen was on board as their boss, Captain Hutchinson.

After CBS ditched "Crimetime After Primetime" in 1993, "Silk Stalkings" moved to USA Network, where it ran until 1999.

Answer: Melanie Chartoff

"Fridays" turned out to be a showcase for talent that went on to bigger and better things, including comedy writer and producer Larry David (of "Seinfeld" and "Curb Your Enthusiasm" fame), comedian Rich Hall (who also appeared on "Saturday Night Live") and comedian Michael Richards (one of the stars of "Seinfeld"). Melanie Chartoff is better known for her work as Principal Grace Musso on "Parker Lewis"; for providing the voice for Didi Pickles, the mother of Tommy and Dil Pickles, on the Nickelodeon show "Rugrats"; and for her recurring role on the CBS show "Newhart" as Dr. Mary Kaiser." In the movie "Man on the Moon", Chartoff was portrayed by comedienne and talk show host Caroline Rhea.

Anne-Marie Johnson, who appeared on the final season of the Fox sketch comedy series "In Living Color", is better known for playing Althea Tibbs on the TV adaptation of "In The Heat of the Night". Nancy Kulp was one of the stars on the long-running comedy "The Beverly Hillbillies".

Answer: Christopher Glenn

New York native Christopher Glenn enjoyed a distinguished career on both radio and television for CBS News between 1971 and his retirement in 2006. In addition to his work on "In The News" and "CBS News Nightwatch", Glenn also served as anchor of the "CBS World News Roundup" on CBS Radio and covered space shuttle launches for the radio network. Glenn was inducted into the National Radio Hall of Fame a couple weeks after his death in October, 2006.

Longtime CBS News correspondent Harold Dow was an original member of the "Nightwatch" team, staying with the show during its first year. Charlie Rose worked on "Nightwatch" from 1984 to 1990 and began hosting his own late-night interview show on PBS in 1991. And Tom Fenton spent much of his time on overseas billets for CBS News, serving as bureau chief in such cities as Rome, Tel Aviv and London before retiring in 2004.

Answer: WRC-TV (Washington, DC)

After spending years as a disc jockey and sports announcer at radio stations in New York and Philadelphia, George Michael landed at WRC-TV in Washington, DC. His Sunday-night wrapup show, called "George Michael's Sports Final", debuted in 1980 and ran as a local show for four years. NBC's other owned-and-operated stations picked up the show, in 1986, at which time the show changed its name. NBC affiliates followed their lead in 1986, and the show earned wider syndication in 1991.

The last original episode aired on March 25, 2007, after Michael refused to renegotiate his contract in the wake of the downsizing of the station's sports staff. George Michael died at age 70 on Christmas Eve, 2009, due to complications from leukemia.

Answer: National Association of Broadcasters

Officially known as the Code of Practices for Television Broadcasters, the Television Code set standards for what constituted ethical television programming for well over 20 years. Among the things prohibited by the Television Code were negative portrayals of law enforcement, family life, and God; use of profanity and illicit sex; and bias in news reporting.

The Seal of Good Practice was often seen at the end of television programs, and individual stations often displayed the seal shortly before signing off for the night.
