Tangled web of advertising: The Pittsburgh Post-Gazette reports on Spider-Man's conquest of Major League Baseball. For the first time, MLB will sell ads on the bases for a Spider-Man 2 movie promotion:

"Home plate will remain untouched, but a Spider-Man logo will be placed on the other bases and in on-deck circles.

"In addition, trailers of the movie, which opens June 30, will be played on ballpark scoreboards."
