WarnerMedia
AOL Time Warner is a megacorporation formed in 2000 by the merger of America Online, the largest internet service provider in the United States and Time Warner, a media conglomerate in traditional paper publishing, film, and television.
The merger was and remains controversial in part due to concerns over monopoly issues (vertical integration), and the collapse of the late 1990s tech industry economic bubble has greatly reduced the company's combined worth.
