I still don't get why Fox wants to sell off their entertainment division. It's not like they're losing money like Sony or Paramount.
It's because those assets are currently devalued in the market place. You really need scale to compete with Netflix or Disney in the movie/tv production space. Fox doesn't have scale like those others do.
Netflix will produce 100 movies a year soon; Netflix will purchase $8+ billion in tv shows and movies next year alone.
Amazon and Apple are heading towards those kinds of numbers. Both Amazon and Apple are each projected to be spending multiple billions on content production by 2020.
Disney has Disney Live Action, Disney Animation, Pixar, Lucasfilm, and Marvel Studios pumping out at least $2 billion in domestic box office and $5 billion in international box office every year.
If you're Fox, those are extremely powerful opponents that they don't have the scale to compete with...
If you look at Fox's stock price, their stock price basically values the entertainment assets as nearly worthless. Almost all of the value in Fox's stock price comes from Fox broadcast, Fox News, and Fox Sports. Why? Because those are Fox's businesses which are defended from competition. Fox's broadcast channel has powerful sports deals (as does Fox Sports), and Fox News has millions of loyal viewers. Those are their strongest, high growth assets.
So think about it, if you're Fox, do you want to get your $20+ billion in value for those slow growth, less competitive assets now, while preventing them from weighing down the rest of the company? This happens in a lot of industries where there's a slow growth division of a company attached to a larger faster growth division.
Typically, the slow growth division gets chopped off and merged with a more sensible partner. Here's an example: United Technologies (a manufacturing/engineering conglomerate) used to own an attack helicopter division, but it sold it recently to Lockheed Martin (a pure defense corporation).
