It looks like Microsoft got some value out of that $10 million it spent to have Seinfeld shill for the company after all. According to Visible Measures, which charts online video viewing trends, the Microsoft commercials starring Seinfeld have been far more popular than the subsequent "I'm a PC" ads.
The videos received an equal number of placements, around 75 each, but Visible Measures found that the Seinfeld campaign had over 4.3 million viral video views more than the "I'm a PC" spots.
The ads starring Seinfeld and Bill Gates have been around longer, but they also beat the newer ads when they hit the market.
There were over 3.2 million viral video views in the first week and a half of the Seinfeld campaign, while "I'm a PC" drew less than half of that. After two weeks of Seinfeld, the spots were still collecting over 700,000 views per day, while the "I'm a PC" ads were down to less than 50,000 views per day.
