Guerila Marketing is not some stealthy, controversial gimmick using street teams –though some of it has been that way. (See MSN’s butterflies, and Sony-Ericsson’s ‘fake tourist’)

It’s often doing the unthinkable, in  a new and unusual way –with an unusual budget, I may add.

Consider what Jetstar, a low-priced airline out of Singapore did to promote low fares. Ogilvy handled a campaign where the airline flew a well-known blind busker to Hong Kong. Beside his instruments was a sign that read "Gone to Hong Kong fpr $48.

For LG Electronics, Ogilvy PR created an outdoor event called ‘Pucker Up New York’ that launched a 76-inch interactive plasma screen at Times Square.
