Film industry

In the United States, movie production has been dominated by major studios since the early 20th century; before that, there was a period in which Edison's Trust monopolized the industry. The music and television industries recently witnessed cases of media consolidation, with Sony Music Entertainment 's parent company merging their music division with Bertelsmann AG's BMG to form Sony BMG and Tribune's The WB and CBS Corp.'s UPN merging to form The CW. In the case of Sony BMG, there existed a "Big Five" (now " Big Four ") of major record companies, while The CW's creation was an attempt to consolidate ratings and stand up to the "Big Four" of American network (terrestrial) television (this despite the fact that the CW was, in fact, partially owned by one of the Big Four in CBS). In television, the vast majority of broadcast and basic cable networks, over a hundred in all, are controlled by seven corporations: Fox Corporation, The Walt Disney Company (which includes the ABC, ESPN, FX and Disney brands), National Amusements (which owns Paramount Global), Comcast (which owns NBCUniversal), Warner Bros. Discovery, the E. W. Scripps Company, Cablevision (now known as Altice USA), or some combination thereof.
