Unlike in American programs, in which bumps are typically supplied by the network (when they have them at all), eyecatches are almost always produced by the production company and considered a part of the program itself, rather than (or also serving as) a segue into a commercial break. They are typically 2–5 seconds long. Eyecatches for children's programs are often longer and more elaborate, while eyecatches for programming for adults may consist of nothing more than the program's logo against a black background.
