The Mary Tyler Moore Show

The pilot for the long-running CBS sitcom The Andy Griffith Show was seen on February 15, 1960, as an episode of The Danny Thomas Show, "Danny Meets Andy Griffith." As originally conceived, Andy Taylor (Andy Griffith) was not only the sheriff of the sleepy North Carolina town of Mayberry, but he was also the mayor, justice of the peace, and newspaper editor. Child actor Ronny Howard (who, as Ron Howard, would in adulthood enjoy a spectacularly successful career as a film director) was seen in the pilot as the widowed Andy's son Opie, but Frances Bavier played an entirely different role than she would in the actual series, while Frank Cady rather than Hal Smith was cast as town drunk Otis Campbell. While there would be changes in concept and casting, the laid-back character of Andy Taylor "clicked" with TV audiences, ensuring that The Andy Griffith Show would join the Monday night CBS lineup come October 3, 1960. Introduced as regulars during season one were of course Andy Griffith, Ronny Howard, and Frances Bavier (now as Aunt Bee, housekeeper for Andy and Opie Taylor), with the significant and salutary addition of Don Knotts as Andy's tightly wound deputy Barney Fife. The rapport between Andy and Barney contributed mightily to the series' success during its shakedown season, with nominal leading character Andy often voluntarily taking a back seat to Barney's overzealous antics. Subsequent additions to the cast included Jim Nabors as bucolic gas station attendant Gomer Pyle (later spun off into his own series, Gomer Pyle, U.S.M.C.); George Lindsey as Gomer's cousin, Goober Pyle; Howard McNear as dithery barber Floyd Lawson; and Hal Smith as the aforementioned Otis Campbell. Taking advantage of Andy Taylor's widower status, the series' writers tried to pair the character off with a number of eligible young ladies, beginning in the first season with Elinor Donahue as drugstore sales clerk Ellie Walker. But only when Aneta Corsaut joined the cast as Opie's schoolteacher Helen Crump did Andy find the "right" girl. Indeed, Andy and Helen would become engaged during the series' final season. Conversely, Barney Fife had but one steady girlfriend, Thelma Lou, played by Betty Lynn. Don Knotts left the series at the outset of its sixth season (the show switched from black-and-white to color at the same time); it was explained that Barney had accepted a deputy position in Raleigh, permitting Knotts to make a handful of memorable return guest appearances. Barney was briefly replaced by Deputy Warren Ferguson, played by Jack Burns; later on, Goober Pyle became Andy's unofficial deputy. The post-Don Knotts episodes brought forth several other new recurring characters: Jack Dodson as town clerk Howard Sprague, Paul Hartman as handyman Emmet Clark, and Hope Summers as Aunt Bee's best friend, Clara. During the Emmy-winning series' eighth season, Andy Griffith decided to leave the show. At this point, Ken Berry was added to the cast as widowed farmer and later town councilman Sam Jones, with Buddy Foster as Sam's son Mike and Arlene Golonka as Sam's girlfriend, Millie Hutchins. After the final telecast of The Andy Griffith Show on September 16, 1968, the series continued for three additional seasons under the title Mayberry RFD, with Ken Berry taking over as star and with most of the familiar Andy Griffith Show supporting characters still in attendance. One of the most consistently popular sitcoms of all time, The Andy Griffith Show lasted 249 half-hour episodes, and also spawned the high-rated 1986 TV movie Return to Mayberry.

One of TV's most durable and wholesome sitcoms is about widower Steve Douglas and his boys, who shared a house with their maternal grandfather, and later, their crotchety uncle. The series was originally scheduled to be a vehicle for the Lennon Sisters of 'Lawrence Welk Show' fame. Characters came and went, but this was an endearing, highly rated series throughout its 1960-72 run; when it moved from ABC to CBS in 1965, Mike, the eldest, was written out, and replaced by adopted son Ernie.

Former 'M*A*S*H' star Wayne Rogers' second medical role was as playboy-surgeon Charley Michaels. When Lynn Redgrave left in a contract dispute, Sharon Gless took over as Charley's love interest.

No one liked Gilligan's Island but the public. Roundly condemned by critics as the worst sitcom in TV history when it first signed on the CBS schedule in the fall of 1964, the weekly half-hour series nonetheless struck a responsive chord with the viewing public, who were thoroughly amused and delighted by the premise of seven diverse personalities shipwrecked on an uncharted tropical island, managing to make the best of things while never giving up hope of being rescued. The series' premise was laid out each and every week by the theme song "The Ballad of Gilligan's Island," co-written by producer Sherwood Schwartz and performed by the singing group the Wellingtons. Caught in a sudden storm at sea, the S.S. Minnow, a tiny charter boat manned by "Skipper" Jonas Grumby (Alan Hale Jr.) and his daffy first mate, Gilligan (Bob Denver), was washed up on the shore of a flyspeck island somewhere in the South Pacific. Marooned along with Gilligan and the Skipper were five tourist passengers: voluptuous movie star Ginger Grant (Tina Louise); multimillionaire Thurston Howell III (Jim Backus) and his wife, Lovey (Natalie Schafer); high-school teacher Roy Hinkley (Russell Johnson), better known as "The Professor"; and wholesomely sexy secretary Mary Ann Summers (Dawn Wells). With the Minnow damaged beyond repair, the seven castaways resourcefully transformed their island into a home away from home, replete with solid shelters, handmade eating and kitchen utensils, jerry-built furniture, and even a farming and irrigation system. Even so, our heroes and heroines yearned to go back to civilization, but they never quite managed to make it, usually thanks to the ineptitude of the feckless Gilligan. Although the seven principals were more or less trapped in their environment, quite a few guest stars managed to find their way on -- and off -- the island, including Hans Conried as klutzy pilot Wrong-Way Feldman, Vito Scotti as mad scientist Boris Balinkoff, and Phil Silvers (who owned a piece of Gilligan's Island in real life) as Hollywood mogul Harold Hecuba. The fact that, for all his brilliance, "The Professor" was never able to figure out how to build a new boat or notify the authorities of the castaways' whereabouts was only a part of the farcical fun; Gilligan's Island was, to overstate the obvious, not exactly like real life. A prime example of good, clean, harmless slapstick, Gilligan's Island confounded its many detractors by remaining on CBS for three seasons, then enjoying a spectacularly successful afterlife in rerun form -- not to mention its many feature-length TV "sequels" (such as The Harlem Globetrotters on Gilligan's Island), two separate TV-cartoon spin-offs, and a multitude of latter-day video retrospectives. It's difficult to argue with that kind of success.

A beloved, multi-Emmy-winning series about Army surgeons cutting up amid the Korean War. For 11 years (10 in the Top 20), the show deftly blended sharp, thoughtful humor with moving scenes of dedicated, stressed doctors trying to save lives---while clinging to their own sanity---in a Mobile Army Surgical Hospital.

Is it possible to continue stoking the flames of a raucous high school romance 15 years after the fact? This was the question posed by the CBS situation comedy Still Standing. Mark Addy and Jami Gertz starred as Bill and Judy Miller, a fun-loving blue-collar Chicago couple who began dating as teenagers and who nearly two decades later were happily married and the parents of three children. So where was the "situation"? Well, it seemed that the Millers still thought and acted like troublemaking schoolkids, which caused any number of amusing crises as they endeavored to properly raise their three children -- notably their nerdish and uptight son Taylor Ball. For the most part, Bill and Judy made up their parental game plan as they went along, though usually things turned out all right. Created by Joey Gutierrez and Diane Burroughs, who based the series on their own enduring romantic relationship, Still Standing originally aired on September 30, 2002.
