Other subchannel-based networks include those that also rely on archived programming such as Buzzr (a network focusing of game shows sourced from the programming library of owner Fremantle Media) and Comet (launched by the Sinclair Broadcast Group and Metro-Goldwyn-Mayer in October 2015, focusing on science fiction series and films sourced from the MGM library), and networks which do not completely if at all rely on archived scripted programming Ion Life (a network carried on Ion Television stations, which mainly airs lifestyle and home improvement programming), WeatherNation TV (an independently owned 24-hour weather network which features subchannels as part of its multiplatform distribution model), TheCoolTV and The Country Network (which rely on music videos).
