What exactly does "ABC" consist of, besides the O&O TV stations. In other words, what is Iger thinking of selling when he says "ABC"
The ABC Television network, for one.
That's ABC News (America This Morning, Good Morning America, World News Tonight, Primetime, 20/20, Nightline, This Week with George Stephanopoulos), ABC Sports (though that's been co-branded with ESPN in recent years), three hours of primetime entertainment seven nights a week, Jimmy Kimmel Live, the Oscars, the Emmys, the American Music Awards and CMA Awards.
ABC also has its own film and television production departments.
It has the rights to films and TV shows, though Disney might want to hold onto those in a sale.
And ABC has online assets, as well.
There are also half a dozen or more buildings the network owns in New York City. Its West Coast operations are on the Disney lot, so there's no real estate involved there---they'd likely move eventually.
