SAN FRANCISCO — Yahoo has acquired Rockmelt, a Silicon Valley startup that built a Web browser tied to Facebook's social network.
Terms of the deal announced Friday weren't disclosed. It's the 20th acquisition that Yahoo Inc. has completed since Marissa Mayer became the Sunnyvale, Calif., company's CEO nearly 13 months ago.
Rockmelt has raised about $40 million from venture capitalists and other investors since its inception. That makes it likely Yahoo had to be above that amount to buy Rockmelt.
