CBS lost much of its ability to broadcast the Super Bowl last Sunday when power to the Superdome went out early in the third quarter due to a suspected malfunction in a device called a relay, the New York Times said. A project that was focused on upgrading the electrical system of the Superdome allowed for the installment of the relay, StarTribune said. The relay was supposed to guard against malfunctions that could occur in the cable that links the power grid with lines that go into the stadium, StarTribune said. The Superdome was using only about two-thirds of its power capacity durning the game, the New York Times said. The relay, being the root cause of the blackout, has since been removed and replaced and according to the officials, "all systems are working now," the New York Times said.
