In television, interstitials refers to short programming which is often shown between movies or other events, e.g a cast interview(s) after movies on Premium Channels. 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 airs Bloopers after shorter than average Braves games.Each interstitial program is three-five minutes in length and is produced in broadcast quality. The interstitial programming is produced in a news-oriented style that documents the issues that impact professionals and consumers alike (much like a network version of what you would find in a trade journal or magazine). Since Public Television is a non-commercial network they do not run commercials. Therefore Public TV utilizes short-form educational segments to use as interstitial programming. These short editorials covering various agricultural, business, medical, and environmental topics, air as stand alone segments in between (interstitially) these major programs.
