Yahoo confirms $1.1 billion Tumblr acquisition

The company said today that "substantially all" of the acquisition was payable in cash, and Tumblr will remain a separate entity.

Microblogging service Tumblr is being acquired by Yahoo.
Yahoo announced the news early Monday, saying that it "promises not to screw [Tumblr] up." The Internet pioneer is paying $1.1 billion for Tumblr, "substantially all of which is payable in cash," Yahoo said.
The news had been expected. The Wall Street Journal reported Sunday that the Yahoo board had approved the deal.
Under the terms of the deal, Yahoo will allow Tumblr, which has over 300 million monthly unique visitors, to operate as a completely separate entity. The company's founder and CEO David Karp will remain in his position.

"Our team isn't changing. Our roadmap isn't changing. And our mission -- to empower creators to make their best work and get it in front of the audience they deserve -- certainly isn't changing," Karp said on Monday in a statement. "But we're elated to have the support of Yahoo and their team who share our dream to make the Internet the ultimate creative canvas. Tumblr gets better faster with more resources to draw from."
Yahoo didn't say specifically what it has planned for Tumblr, but did say that the service's more than 50 billion blog posts are valuable additions to Yahoo's services and search. In a conference call discussing the acquisition, Yahoo CEO Marissa Mayer said that she plans to integrate Tumblr in to Yahoo's home pages.
"The two companies will also work together to create advertising opportunities that are seamless and enhance the user experience," Yahoo said. Mayer was similarly less-than-forthcoming in her conference call on exactly how Yahoo will create new advertising opportunities, but she did say that she hopes to make ads "aspirational."
This is the first time that Yahoo made a play for Tumblr. A report back in 2009 suggested that Yahoo was in talks with Tumblr to acquire the company for "as much as $50 million." At that time, Karp said that Yahoo wasn't going to buy Tumblr at that time. If those talks did, in fact, happen, it looks like Karp made the right deal.
The Tumblr deal is subject to customary closing conditions. If all goes well, the deal should close in the second half of 2013.
