That cat's out of the bag a day early, it seems. Yahoo's board has approved a $1.1 billion cash deal to purchase the blogging site Tumblr, according to The Wall Street Journal. We were expecting Yahoo to announce the acquisition during tomorrow's NYC media event -- CEO Marissa Mayer may instead use the last-minute gathering to detail the company's plans for integrating the popular platform. It's unclear how Yahoo intends to utilize its latest procurement, but with a 10-figure price tag now public, we can only imagine that Tumblr will be put to good use. We'll be covering tomorrow afternoon's event live, so stay tuned for more details from New York City.
