Associated Press: Google has never disclosed how much money YouTube brings in or even if the video site is profitable. The research firm eMarketer projects YouTube will sell about $4.3 billion in advertising this year, after subtracting commissions and licensing fees. That would translate into about 7 percent of Google’s projected revenue of $60 billion this year after subtracting advertising commissions. If it were an independent company, YouTube likely would be worth at least $20 billion, based on investors’ assessment of Netflix, the Internet’s leading video subscription service.
