BennyBaby makes some big claims regarding the affect his videos have on the service. He estimates his videos generate about 11,200 views per day, and that would entitle him, apparently, to an unquestionable 1/9000th of the overall revenue. The lawsuit goes on to round this percentage down to 1/500th due to spam and porn videos it claims are flooded onto he service.
It continues to compare this 1/500th estimate with the $1.5 billion deal that Google agreed to in acquiring YouTube to justify valuing the videos at $3.6 million. Of course, it seems highly unlikely that BennyBaby will be successful as Google's Partners are chosen because they have enormously high amount of views and usually a lot of subscribers; far more than what BennyBaby's comedy videos offer.
UPDATE: It was pointed out that many partners have generated less views and have less subscribers than Ligeri. The criteria by which YouTube chooses partners is not very clear however, and does not provide a specific threshold by which to compare an account.
The lawsuit makes a reference to the $1 billion Viacom lawsuit against Google, but there is simply no comparison as BennyBoy provides these videos for free knowingly on YouTube, whereas Viacom does not, and instead takes issue with the uploading of its content by users of the service, claiming copyright violations.
