The Super Bowl frees us up to shamelessly marvel at bigness. Sports fans and those among us with a penchant for big shiny things look forward to the scale of its fanfare, no matter who's playing. Media economists in our midst keep their fingers on the pulse of the big buy -- noting which advertisers are doing what for the big game, and what kind of bellwether that activity might be.
