mcflaherty writes "The Federal Trade Commission has stated that it is going to investigate the use of 'Viral Marketing' by corporations. This is the type of advertising that seeks to start a word of mouth campaign for the product via consumers themselves. Previously, consumers themselves set the buzz. But lately advertisement firms are stepping up to the plate themselves, seeding the market with buzz that looks independent of the company, but is in fact funded by them. The crew at Penny Arcade contend that corporate generated buzz is not Viral Marketing, and perhaps Guerrilla Marketing would be a more apt term. Either way, it appears to be a profitable advertising model."
