"Virtual advertising has so far been a novelty feature of live sports, where football players tackle each other in front of make-believe billboards and soccer players run across plausibly real trademarks. For example, the games of three Major League Baseball teams—the San Francisco Giants, Philadelphia Phillies and San Diego Padres—include virtual ads this season."
—Stuart Elliot, "Real or Virtual? You Call It," The New York Times, October 1, 1999
