TGIF was an American prime time television programming block that aired on ABC at various points starting in the late 1980s. The name comes from the initials of the popular phrase "thank God it's Friday"; however, the stars of the lineup touted the initialism as meaning "Thank Goodness It's Funny." In its various incarnations, the block mainly featured situation comedies aimed at a family audience, and served as a lead-in to the long-running newsmagazine 20/20 (which has been part of ABC's Friday-night schedule since September 1987, two years prior to the original launch of TGIF).

The block initially premiered on September 22, 1989, as a partnership with Lorimar Television and television producers Thomas L. Miller and Robert L. Boyett (who had a deal with Lorimar), marking one of the first attempts by a major network to brand a programming block (a concept that was concurrently becoming popular among cable networks at the time of its inception), with the goal of encouraging young viewers to watch the entire lineup and not just a particular show. The TGIF block dominated the ratings in the 18–49 demographic for most of the 1990s. However, ratings began declining during the latter half of the decade due partly to Fridays becoming more common for social outings among segments of the block's key demographic as well as the loss and aging quality of many of the lineup's signature shows, culminating in the end of the original incarnation after eleven years on September 8, 2000.

ABC revived the TGIF brand on September 26, 2003, with its second run lasting only two seasons, ending on September 15, 2005. On May 15, 2018, ABC announced that it would revive the block, with the third incarnation, which was launched on October 5, 2018. This newest incarnation of TGIF consisted of a mix of sitcoms and game shows. The incarnation was short-lived, with the block ending for the third time on September 27, 2019.

History

ABC Friday-night legacy: 1950s to 1970s Family-friendly comedies, which featured families with children as major characters, were a staple of ABC's programming dating back to the network's earlier sitcoms from the 1950s onward, such as The Adventures of Ozzie and Harriet (which premiered in 1952), Leave It to Beaver (which moved to ABC in 1958, after spending its first season on CBS), The Donna Reed Show (which premiered in 1958), The Flintstones (which premiered in 1960, but was largely an adult-oriented animated comedy until the birth of Pebbles in 1963), The Brady Bunch (which premiered in 1969), and The Partridge Family (which premiered in 1970; that series and The Brady Bunch became part of the Friday night lineup at that time).

Jim Janicek TGIF was created and executive produced by Jim Janicek. Prior to the official launch of the block, Janicek was employed as a writer and producer for ABC Entertainment, who was in charge of promoting the network's Tuesday- and Friday-night comedy lineups. Recalling his childhood when his family would gather to watch The Wonderful World of Disney, he was inspired to create a family-oriented comedy block. In 1988, Janicek began gaining support for his concept by approaching the studios and talent of independently produced ABC shows, promoting the synergy and potential success of the family block brand. With four ABC family-oriented comedy series on board, and the backing of network president Bob Iger, the initial lineup for the block was created.

Before ABC experienced its success on that night during the 1980s, its Friday night schedule consisted of hit comedies such as Webster (which remained on Fridays until its cancellation by ABC in 1987, only to subsequently be renewed by Paramount Television as a first-run syndicated series), Benson (which would be cancelled at the end of the 1985–86 season) and Diff'rent Strokes (which moved to ABC in 1985 after being cancelled after seven seasons by NBC, only to cancelled by ABC following its eighth and final season). The block of predominantly family-friendly situation comedies was inaugurated in the 1988–89 season with three series that were already part of the Friday lineup (Perfect Strangers, Full House and Mr. Belvedere) and a sophomore series new to that night, Just the Ten of Us (a spinoff of Growing Pains, which originally aired on Tuesdays for its abbreviated first season in the spring of 1988).

Since the 1987–88 season, Perfect Strangers stars Mark Linn-Baker and Bronson Pinchot (in character as Larry Appleton and Balki Bartokomous, respectively) had been doing hosted interstitials that were conducted from the Perfect Strangers set, originally airing during the two-hour Wednesday sitcom block that their series was part of as that season began. In March 1988, Perfect Strangers moved to Fridays, and the interstitials went with them. On Fridays, the hosted interstitial concept gained more traction before the family-friendly concept on that night was actually implemented. Pinchot and Linn-Baker would remain the sole hosts of the Friday lineup throughout the 1988–89 season.

Meanwhile, ABC began reformulating its Tuesday night lineup which, for the past several seasons, had consisted of a comedy block from 8:00 to 9:00 p.m. Eastern Time followed by two hour-long dramas, most notably with the hit series Moonlighting airing at 9:00 p.m. Eastern. Moonlighting, then in its fifth season and starting to experience a considerable decline in its ratings (greatly thanks to the 1988 WGA strike, which delayed the premieres of many programs set to launch or return for the 1988 fall season), was placed on a temporary hiatus by ABC in February 1989 when the network decided to add a second hour of comedy offerings onto its Tuesday schedule. Janicek, in response, came up with the idea to promote the restructured lineup under a unified brand name, Terrific Tuesday, to draw audiences to the changes, to reference the two additional sitcoms that were being offered, and especially as a nod to Who's the Boss? and the freshman smash hit Roseanne, which now served as a strong anchor for the expanded comedy lineup.

The Terrific Tuesday branding was a success, and ABC urged Janicek to continue the banner name for the following season. At the time of the network upfronts that unveiled the upcoming fall schedule in May 1989, Janicek, as well as ABC, devised the notion of further promoting their family fun-themed Fridays with a brand name. Over the summer, ABC began promoting the Friday sitcoms under the experimental title, "The Friday Fun Club". While Terrific Tuesday and What-a-Wednesday were both on tap for the 1989–90 fall season, the Friday branding concept was to undergo a revision before September.

First run (1989–2000)

Brand debuts

As a result of ABC and Jim Janicek's plan for Friday brand familiarity, definitive changes occurred to the lineup on Friday, September 22, 1989. An opening sequence for the two-hour block was introduced, featuring animated mice against a gray background. The theme music, featuring a male vocalist and a falsetto-tuned backup chorus, sang the lyrics, "Time for fun (thank goodness!)/Time for a good laugh (it's funny!)/Time, time, time, time for fun! (T-T-T-Time!)". The mice held up title cards containing the selected theme lyrics "Thank goodness" and "It's funny!" right in the way of an older mouse. The sequence concludes with the older mouse breaking a grandfather clock with a mallet, which cut to the hosted interstitial.

For the first time, another show's cast assumed hosting duties for the interstitials in place of the stars of Perfect Strangers. Dave Coulier, John Stamos and Mary-Kate and Ashley Olsen (alternating as Michelle Tanner) all appeared on the set of Full House introducing the season and series premieres that night. As they began their first segment, the TGIF name was officially introduced, in which its meaning, "Thank Goodness It's Funny", was re-emphasized from the theme lyrics. Coulier and Stamos also announced that a new policy, in which stars from the other three TGIF programs would rotate hosting responsibilities along with them on a week-to-week basis, would begin. Rotating with Full House that season were the casts of new arrival Family Matters, Perfect Strangers (whose first night its cast members hosted the Friday lineup under the TGIF banner occurred on October 13, 1989) and Just the Ten of Us. On the premiere night of TGIF, the new (and ultimately short-lived) comedy Free Spirit aired as a preview telecast at 9:30 p.m. Eastern Time, with Just the Ten of Us reclaiming its time slot the following week.

During the inaugural season of the format, the TGIF logo was only featured at the start of every hosted segment, appearing in a design where each letter was encased in a tall gray box (as pictured to the right); the boxes would flip in at the bottom of the screen, stand still for a few seconds, and then turn out. One of the animated mice from the TGIF title sequences was featured on some weeks within the live-action host segments, and was introduced by the actors as the lineup's mascot, known as "Friday the Mouse". Custom bumpers would appear after the final scene of each program, where normally a short cut of the show's title logo and theme would play, denoting the final commercial break.

During the first season of TGIF, the bumpers featured additional animations of the mice, including variants that featured the taller mouse popping out of the grandfather clock, a small mouse being dragged around by a running chainsaw around it, the taller mouse walking towards the grandfather clock, thinking it over, and then backtracking, and the taller mouse popping up from the top and bottom of the screen on both sides of the show's title logo. The official title logo for the respective program (as opposed to the logo designs used mainly in network promotions for each show that were used in the block's bumpers in later years) was displayed on either side of the clock. The closing animation, which ran after the credits of the 9:30 program (usually Just the Ten of Us), consisted of the same theme music, albeit with the lyrics, "See you next week... here for a good laugh", followed by a few instrumental notes. One such animation involved the taller mouse holding what looked like a parade float likeness of himself, as it flies out of control and he flies around with it. Another shows the mouse walking with a blowtorch and mask on, but he doesn't know that the plug comes lose, so he angrily walks back.

Explosive success in the 1990s With the TGIF moniker permanently in place, more changes in presentation occurred as the lineup grew in popularity. On September 21, 1990, the animated mice opening and accompanying theme music were dropped from the Friday block, in favor of a new graphics package that officially incorporated the new TGIF name for the first time. With these new visuals came the "classic" TGIF theme ("It's Friday night/And the mood is right/Gonna have some fun/Show you how it's done, TGIF.").

For most of TGIFs run until the 1998–99 season, at least one series on the lineup was produced (and in some cases, developed) by the team of Thomas L. Miller and Robert L. Boyett, whose relationship with ABC traces back to the premiere of Love, American Style – produced by Miller and former producing partner Edward K. Milkis under a development deal with Paramount Television – in 1972. The first two series were Perfect Strangers and Full House, both of which were produced through Miller-Boyett's development deal with Lorimar Television (absorbed into Warner Bros. Television in 1993) and aired on the network's Friday night schedule prior to the launch of TGIF. (The latter premiered in September 1987 as part of the network's Friday schedule, while the former concurrently was moved from Wednesdays to Fridays that month.)
