In television programming, an interstitial program (or wraparound program or wraparound segment) refers to a short program that is often shown between movies or other events, e.g. cast interviews after movies on premium channels. The term can also refer to a narrative bridge between segments within a program, such as the live action introductions to the animated segments in the Disney films Fantasia and Fantasia 2000, or the Simpson family's interludes during their annual Treehouse of Horror episodes.
Sometimes, if a program finishes earlier than expected, a short extra program may be inserted in the schedule to fill the time until the next scheduled program is due to start. American cable channel TBS commonly aired TV's Bloopers & Practical Jokes after shorter-than-average Braves games.
For U.S. telecasts of the film The Wizard of Oz between 1959 and 1968, celebrity hosts appeared in wraparound segments. Opening credits especially designed by the network were shown in CBS's own format, followed by the host's first appearance, in which he made comments (often humorous, though never derogatory) about the film. Immediately following this, and without a commercial pause, the film itself would begin with all of its original 1939 opening credits. Halfway through the picture, the host would reappear and introduce the second half of the film. When the film ended, however, its closing credits would not be shown in their original format. Instead, the host would appear once more, bid farewell to the viewing audience, and the closing credits would be shown in CBS' own format.
Raidió Teilifís Éireann in the Republic of Ireland used a variety of material as interstitials; often animation, including Roger Mainwood's video of Kraftwerk's hit "Autobahn", Halas and Batchelor shorts, and stop-motion Soviet cartoons; also rhythmic gymnastics performances, instrumental music, or sometimes simply a test card.
Japanese public broadcasting organization NHK's Minna no Uta is something of a national institution, commissioning makers of usually animated films and famous or upcoming music acts to collaborate on exclusive music videos used to plug schedule gaps in lieu of advertisements.
