An anonymous reader writes "It's reported that Yahoo has formally put in a bid to buy Hulu only a week after adding Tumblr to the family. From the article: 'Yahoo just spent $1.1 billion of its cash hoard to acquire Tumblr, a blogging site with 300 million mostly young-ish visitors and 24 billion minutes of usage per month. Yahoo CEO Marissa Mayer's team can slap a lot of tasteful, personalized native ads into the Tumblr content streams to monetize the fast growing site. It's the same way that Facebook and Twitter hope to get into the tens of billions in revenue league, but it's a long and winding road. Now Yahoo is taking a run at Hulu, with its 4 million subscribers paying $7.99 per month, original programming , and more than 70,000 full TV episodes. Hulu could immediately put Yahoo's video efforts and revenue in a different league.'"
