Comet is an American digital broadcast television network owned by the Sinclair Television Group subsidiary of the Sinclair Broadcast Group. The network focuses on science fiction with some supernatural, horror, adventure and fantasy series and films, sourced mainly from the Metro-Goldwyn-Mayer film and television library. Sinclair also owns Charge!, Stadium and TBD broadcast networks. Comet is also available via streaming services, Apple TV, FuboTV, YouTubeTV, Roku, Sling TV Satellite Company Dish Network channel 289 and Sinclair's Stirr.
On June 29, 2015, Metro-Goldwyn-Mayer and the Sinclair Broadcast Group's broadcasting and programming subsidiary Sinclair Television Group, Inc. announced the expected 4th quarter launch of the then-unnamed science fiction network. Sinclair chief operating officer David Amy, in announcing the partnership, noted that MGM "has an extensive collection of science fiction films and television movies that appeal to a vast audience who will now be able to access that content through broadcast television". Sinclair tapped its television stations in many of the 79 markets where the company owned or operated a broadcasting property at the time of the announcement to serve as the network's initial charter affiliates. On August 5, 2015, in its financial report for the second fiscal quarter, Sinclair Broadcast Group announced that the new network would be named Comet.
