Amc Global Media Inc.
A global media and entertainment company that makes and distributes television and film, best known for producing hits like *The Walking Dead*, *Mad Men*, and *Breaking Bad* through its AMC Studios arm, and for running streaming services such as AMC+, Shudder, and Acorn TV. Its roots reach back to 1980, when a New York-area service called "Montage" launched the channel that became AMC (American Movie Classics); the business was spun off from Cablevision in 2011 and in April 2026 rebranded from AMC Networks to AMC Global Media to signal its shift toward streaming and global operations.
