This is terrible. Disney owns too many IPs and pop culture assets. This also gives the Avatar, The Simpsons, Ice Age, Planet of the Apes, The X Files, Archer, Bob's Burgers, Family Guy, and much more. People celebrating X-Men and F4 in the MCU are shortsighted. Too much corporate power.

It's not a blanket sale of the entire company:

"The Disney/Fox deal would not be a complete purchase of 21st Century Fox. What's not likely to change, according to CNBC: The local Fox broadcast channel (home of Sunday NFL football and popular television shows The Simpsons and Family Guy), the company's affiliate networks and Fox News, Fox Business and Fox Sports 1 cable channels. These assets are said to remain with whatever is left of 21st Century Fox."

Disney has 3 major reasons behind this acquisition, and all of them tie into assets they currently own a sizeable stake in:

1)  Unification of the MCU
2)  Fox's perpetual rights to Star Wars: A New Hope revert to Disney, giving Disney rights to all of the Star Wars films.
3)  Increasing stake in Hulu to majority share

I'm more worried about 2019 when the Disney/Netflix deal comes to an end. Disney wants to create a service similar to Netflix but I don't see why I should pay twice to get the same content I have today with Netflix only.

EDIT: Wait a second, if Disney acquires 21st Century Fox, they can take even more stuff out of Netflix? This is bad, very bad.

Disney might just be looking to make Hulu their streaming service rather than build a new one up from scratch.  They already have content on Hulu, and also own a 30% stake.  By buying Fox's 30% stake in Hulu as well, they will have majority stake in the platform.

"By acquiring Fox's stake, Disney would up its share in the streaming platform to a majority 60% share. With Disney already announcing plans to launch a non-sports streaming platform in 2019, it is possible the company will instead look to transform Hulu into this platform, or at the very least give itself another pawn in the future streaming media battle."
