Associated Press reports:
NEW YORK (AP) — A power outage during the Super Bowl sent CBS scrambling and knocked its announcers off the air.
The biggest broadcast event of the year was suddenly jolted by silence and darkness when a portion of the Super Dome in New Orleans lost power early in the game's second half. CBS' announcers, Jim Nantz and Phil Simms, were part of the outage and unable to explain the situation to viewers.
That led to an awkward, ambient few moments in a broadcast that's otherwise nonstop noise.
Eventually, CBS sideline reporter Steve Tasker announced the problem of a "click of the lights" to viewers. Later, the halftime crew anchored by host James Brown returned to fill the time with football analysis. Brown said a power surge caused the outage.
