ABC News is the news division of the American Broadcasting Company (ABC), owned by the Disney Media Networks division of The Walt Disney Company. Its flagship program is the daily evening newscast "ABC World News Tonight"; other programs include morning news-talk show "Good Morning America", newsmagazine series "Nightline", "Primetime" and "20/20", and Sunday morning political affairs program "This Week with George Stephanopolous". 

ABC began news broadcasts early in its independent existence as a radio network after the Federal Communications Commission (FCC) ordered NBC to spin off the former NBC Blue Network into an independent company in 1943. The split (which NBC conducted voluntarily in the event that its appeal to have the ruling overturned was denied) was enforced to expand competition in radio broadcasting in the United States as the industry had only a few companies such as NBC and CBS that dominated the radio market, and in particular, was intended to prevent the limited competition from dominating news and political broadcasting and projecting narrow points-of-view. Television broadcasting was suspended, however, during World War II. 

Regular television news broadcasts on ABC began soon after the network signed on its initial owned-and-operated television station (WJZ-TV, now WABC-TV) and production center in New York City in August 1948. ABC news broadcasts have continued as the television network expanded nationwide, a process that took many years beginning with its launch in 1948. However, from the 1950s through the early 1970s, ABC News' programs (as was the case with the television network in general during that period) consistently ranked third in viewership behind news programs on CBS and NBC. Until the 1970s, the ABC television network had fewer affiliate stations, as well as a weaker prime-time programming slate to be able to truly support the network's news operations in comparison to the two larger networks, each of which had established their radio news operations during the 1930s.
