Comet is an American digital broadcast television network owned by the Sinclair Television Group subsidiary of Sinclair Broadcast Group and operated by the MGM Television division of Metro-Goldwyn-Mayer, which focuses on science fiction and supernatural programming. As of March 1, 2017, Sinclair has made the network's live stream available as an app on the Apple TV and Roku digital media player platforms (and in 2019 Sinclair's Stirr service also carries the network), allowing viewers without an over-the-air affiliate to view Comet's programming.
