Media cross-ownership is the common ownership of multiple media sources by a single person or corporate entity. Media sources include radio, broadcast television, specialty and pay television, cable, satellite, Internet Protocol television (IPTV), newspapers, magazines and periodicals, music, film, book publishing, video games, search engines, social media, internet service providers, and wired and wireless telecommunications.

Much of the debate over concentration of media ownership in the United States has for many years focused specifically on the ownership of broadcast stations, cable stations, newspapers, and websites. Some have pointed to an increase in media merging and concentration of ownership which may correlate to decreased trust in 'mass' media.

Ownership of American media Over time, both the number of media outlets and concentration of ownership have increased, translating to fewer companies owning more media outlets.

History of FCC regulations The First Amendment to the United States Constitution included a provision that protected "freedom of the press" from Congressional action. For newspapers and other print items, in which the medium itself was practically infinite and publishers could produce as many publications as they wanted without interfering with any other publisher's ability to do the same, this was not a problem.

The debut of radio broadcasting in the first part of the 20th century complicated matters; the radio spectrum is finite, and only a limited number of broadcasters could use the medium at the same time. The United States government opted to declare the entire broadcast spectrum to be government property and license the rights to use the spectrum to broadcasters. After several years of experimental broadcast licensing, the United States licensed its first commercial radio station, KDKA, in 1920.

Prior to 1927, public airwaves in the United States were regulated by the United States Department of Commerce and largely litigated in the courts as the growing number of stations fought for space in the burgeoning industry. In the earliest days, radio stations were typically required to share the same standard frequency (833 kHz) and were not allowed to broadcast an entire day, instead having to sign on and off at designated times to allow competing stations to use the frequency.

The Federal Radio Act of 1927 (signed into law February 23, 1927) nationalized the airwaves and formed the Federal Radio Commission, the forerunner of the modern Federal Communications Commission (FCC) to assume control of the airwaves. One of the first moves of the FRC was General Order 40, the first U.S. bandplan, which allocated permanent frequencies for most U.S. stations and eliminated most of the part-time broadcasters.
