There is no reason why TV networks need to exist the way they do. Hulu, Netflix and Amazon all produce original content and are perfectly positioned to disrupt them as their distribution volume increases. Even the current distribution channel is being disrupted by Aereo. Hulu is a a huge asset.
If Yahoo gets in this game, they have a massive number of users, photos (flickr), blogposts (tumblr), mail, content... they're rivaling the reach and diversity of Amazon and Google as content owners (though without their respective cash cows of b2c sales and ads).
What's next? Is there some sort of connection that I'm missing between flickr, tumblr, the existing yahoo platform and hulu? Do they buy vimeo from IAC, or buy/merge with IAC? What's the strategy behind all the acquisitions?
