The problem is most of those companies are suffering. They are merging because they can't grow any further. Heck, now several companies are directly part of each other. MSNBC is now over Universal Films and Theme Parks. The Theme Parks have very little to do with the News or TV shows. Films by Viacom are all considered part of the same past a certain point of Bureaucracy.

It's happening like this to all of the companies. Warner Bros is probably up for sale. Paramount just sold for $8 Billion. Nickelodeon is trying to have a new theme park without the requirements that Universal have them back in the day. It's a very weird and slowly collapsing system.
