Super Bowl 50 is still a ways away. But the money is already flowing in. The host committee that’s been tasked with bringing the National Football League’s biggest event — and the most-watched television spectacle in the United States — to the San Francisco 49ers’ new stadium in Santa Clara announced that it had raised $40 million toward that end. Tech companies have pitched in big to bring the game to Silicon Valley, with Yahoo, Google, Apple and Intel all pledging $2 million in “cash and other services,” according to reports.
