Since the early 1980s, Showtime has run an adult-oriented late night programming block on its main channel called "Showtime After Hours" (which was briefly branded as "Showtime Late Night" during the mid-1990s) each night after 12:00 a.m. Eastern Time; programs featured within the block include feature films, series produced specifically for broadcast during the block and occasional stand-up comedy specials. Softcore erotica programming has previously aired during the "After Hours" block, though adult films have been absent from Showtime's primary channel since the mid-2000s; the network began broadcasting a limited amount of original erotica series (such as "Beach Heat: Miami") on its main channel in 2010, after having been absent for most of the previous decade. The network's multiplex channels Showtime 2 and Showtime Extreme also occasionally feature adult films during the overnight hours, though this has become less commonplace since late 2011.
