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 (TV series)|Free Spirit]]'' aired as a preview telecast at 9:30&nbsp;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.
