carried (either presently or in the past) adult films or series. There are 24-hour pay services dedicated to pornographic content that also exist, operating similarly to the pay-per-view model (such as Playboy TV and the more hardcore pornography Spice Networks), which television providers typically sell as nighttime-only packages. Premium channels also run older, lower-profile or obscure feature films (that either received home video, DVD or theatrical release, and often featuring a release lag of up to 30 years) during the overnight hours; these are sometimes interspersed with more recent films, specials and reruns of original series. Some pay services embraced the rise of videocassette recorder in the 1980s and 1990s by promoting the use of recording overnight films for later viewing; The Movie Channel was one such adopter, as from 1986 to 2004, it carried a daily (later weekly) block called "VCR Theater" (later renamed "VCR Overnight" in 1988 and "TMC Overnight" in 1997). Most American cable channels often air either blocks of infomercial or timeshift channel of prime time programming during late night time periods (the use of replays is most commonly used by cable news channels), while only a handful of basic cable channels (such as TNT, Nickelodeon/Nick at Nite and ESPN) maintain a round-the-clock schedule incorporating entertainment programming during the overnight hours.
