TLC is an American multinational cable and satellite television network owned by the Networks division of Warner Bros. Discovery. First established in 1980 as The Learning Channel, it initially focused on educational and instructional programming. By the late 1990s, after an acquisition by Discovery, Inc. earlier in the decade, the network began to pivot towards reality television programming—predominantly focusing on programming involving lifestyles and personal stories—to the point that the previous name with "The Learning Channel" spelled out was phased out in favor of its initialism.
As of November 2023[update], with its programming primarily dedicated to the nine-series 90 Day Fiancé universe, comprising 31% of the shows carried by the channel, TLC is available to approximately 71,000,000 pay television households in the United States—down from its 2011 peak of 100,000,000 households.
