NFL: Beyonce didn't make the lights go out during the Super Bowl

Don't blame Beyoncé for the Super Bowl blackout.

That's the NFL's stance on the half-hour delay when the Superdome went dark, adding that it launched a probe into what caused the lights to go out at one of the world's most watched and meticulously planned events.

"There's no indication at all that this was caused by the halftime show," NFL commissioner Roger Goodell said Monday. "I know that's out there, that Beyoncé's halftime show had something to do with it. That is not the case from anything we have at this point."

With more than 108 million Americans watching along with television viewers in 180 countries, about half the stadium lights went dark early in the second half of the game, in which the Baltimore Ravens defeated the San Francisco 49ers, 34-31.

The outage "was on an epic scale for them (organizers) across the board. They start planning Super Bowls approximately four to six years out. It's the same thing with Olympic committees," said Dave Longwill, vice president for special events at TBA Global, which stages large events and worked on the game in New Orleans.

"I'm sure they're already looking at reviewing what's our contingency plan if this happens at the next one," he said.
