The Super Bowl not only means tens of millions of dollars to the network that carries it, but it means far more than that to the manufacturers of big-screen TV sets. The Consumer Electronics Association said that wholesalers will likely gross $2.2 billion from the 2.4 million HDTV sets that are expected to be sold in advance of Super Bowl XLII. Retailers, it noted, will benefit not only from sales of the sets but ancillary items such as surround-sound audio systems, cables, mounting brackets, etc. The CEA also observed that its expects 18 percent of those watching the game on TV will have a laptop PC nearby to check statistics and betting lines and send instant messages to friends who are also watching the game.
