TBS is known for two things: sports and comedy. The Turner channel famously airs the Stanley Cup Playoffs, All Elite Wrestling matches, March Madness, a couple of NBA games, and more postseason MLB games than any other network. On the comedy side, it's home to reruns of Warner classics like Modern Family, Friends, Young Sheldon, and American Dad. Not a lot of originals, but it combines the best of both worlds for a lot of people.
