As of my last update in early 2023, Tyler Perry does not own BET (Black Entertainment Television). BET is a cable channel that focuses on programming targeting African American audiences, and it is owned by ViacomCBS, which is a major media and entertainment company formed from the merger of Viacom and CBS Corporation.
Tyler Perry is a well-known American actor, director, producer, and screenwriter, best known for his work in film and television, often involving his alter ego, Madea. While he has been involved in various media ventures and has his own production company, Tyler Perry Studios, he is not the owner of BET.
