Team Fill-in-the-Blank

[Leslie Savan]

       Does anyone have an idea of when or how this construction began to really catch on?: "Team Obama," "Team Macintosh," "Team Get er Done" on MySpace, "Team Guido" (not the Guido team or the Guidoes) on The Amazing Race. "Team Toyota" is a 1996 book, but surely Team X goes much further back.
       It undoubtedly got a big boost from businesses trying to stoke as much team spirit as sports teams: "Meet Team Target--Targeting Your Real Estate Needs." But who initiated the switch from the X team to Team X: the businesses? Sports commentators, sports teams themselves? (I know nothing about sports, so this may be obvious to all but me). And/or is there a Superhero connection?
       Any ideas from Team ADS are much appreciated.
