LOS ANGELES (REUTERS) - The Super Bowl averaged 114.4 million viewers on Sunday, making it the most-watched telecast in US television history, broadcaster NBC said according to Nielsen data.

The New England Patriots' 28-24 win over the Seattle Seahawks in the final seconds of the NFL championship game topped last year's record Super Bowl, which drew an average of 112.2 million live viewers.

Also attracting viewers was a eye-opening hi-tech, high-energy half-time spectacle starring pop star Katy Perry that many compared to the increasingly-elaborate opening ceremonies of the Olympics, and the roll-out of a non-stop series of expensive new commercials by advertisers hoping to brand their product names into the minds of viewers.
