Disney already owns ABC, ESPN, LucasFilm, and Marvel Entertainment.
I see regulatory issues with this.
Combining Fox TV (not the news assets) and ABC under a single owner will be a tough sell.
Do you think Comcast would have the same issues if they bought it? NBC, Universal, etc..they own a bunch....
