…and what are NBC and ABC?
When referencing these networks…for example, when talking about CNN’s increasingly-extreme political bias, ABC’s running of a video supposedly from Syria which was actually from Kentucky, or the reports about widespread abuse of women at NBC, people tend to simply refer to them as “CNN”, “ABC”, or “NBC”, as if they were independent entities. But they’re not.
CNN is owned by AT&T. NBC is owned by Comcast, and ABC is owned by Disney.
The history is that CNN was part of Turner Broadcasting, which merged with Time-Warner in 1996. Following a whole host of acquisition and divestiture transactions (which included a very expensive experience with AOL), Warner Media was acquired by AT&T in 2018. NBC was acquired by GE in 1986 as part of its reacquisition of RCA; the networks was put into a joint venture with Comcast in 2009, and the GE share of the venture was bought out by Comcast in 2013. Disney acquired ABC in 1996 as part of its acquisition of Capital Cities/ABC Inc.
Given how these entities have been shuffled around, it may be understandable that people refer to them simply by the names of the networks; still, I think the proper way to refer to CNN would be “CNN, a subsidiary of telecommunications giant AT&T” and similarly for the others.
