Warner Bros. was founded in 1923 by four Polish immigrant brothers in Ohio who began exhibiting movies and later moved into film production and distribution. Headquartered in Burbank, California and New York, it is now a major American film, television, and music studio and subsidiary of Time Warner. Over the decades through mergers and acquisitions, Warner Bros. has accumulated a diverse collection of films, cartoons, and television shows, including owning the rights to major franchises like Harry Potter and Batman.
