Regular ABC television news broadcasts began soon after ABC started transmitting from its initial New York City television station and production center in late summer 1948. ABC-TV news broadcasts have continued as the ABC television network spread across the country, a process that took many years, from that beginning in 1948 through today, but they have not always had the same level of success that they enjoy now. Throughout the 1950s, the 1960s, and the early 1970s, ABC News consistently ranked third in viewership behind CBS News and NBC News. Until the 1970s, the ABC-TV network had fewer affiliate stations, and also weaker prime-time programming lineups to support the network’s news departments than the two larger networks had, each of which had established their radio news operations during the 1930s.

Only after Roone Arledge, the former head of ABC Sports, became the president of ABC News in 1977, at a time when this network’s prime-time entertainment programs were achieving good ratings and drawing in advertising revenues and profits to the ABC corporation overall, was ABC able to invest the resources to make it a major source of news telecasting. Arledge, known for experimenting with the broadcast “model”, created many of ABC News’s most popular and enduring programs, including 20/20, World News Tonight (now ABC World News), This Week, Nightline, and Primetime Live.

ABC News gained respect in the early 1980s by covering the Iran hostage crisis and, later, for covering the 1989 Loma Prieta earthquake in the San Francisco Bay Area with live telecasts.

The ABC News slogan, “More Americans get their news from ABC News than from any other source”, is a claim that refers to the number of people who watch, listen, and read ABC News programming on television, the radio, and the Internet, and not necessarily to the telecasts alone.^[1]

ESPN, a sports-news organization with several cable and satellite television channels — and also owned by Disney — provides sports bulletins and video for some of ABC News’s programs, especially the overnight programs.
