Irvine-based VIZIO announced this morning that it has tapped Beyonce Knowles as the spokesperson for the firm, and will launch a Super Bowl spot featuring the artist during Super Bowl XLIV. According to VIZIO, a major manufacturer of high definition TVs, the firm's Super Bowl ad will run during CBS in-game coverage of the game, and that it will also be the exclusive HD sponsor of the CBS Super Bowl Pre-Game Show. VIZIO did not say what it plans to spend on its Super Bowl push, but said it will air a 60-second spot in the fourth quarter, and two 30-second spots during the pre-game show. A 30-second spot in the Super Bowl this year is expected to cost $2.5M to $2.8M apiece. VIZIO also advertised on last year's Super Bowl.
