Surpassing rival Microsoft's 547 million in total number of videos served, the three-year old YouTube says they've now passed the 1 billion per day mark.

Previously, comScore had reported numbers for their U.S. market to be in the neighborhood of 10 million videos watched per month, however, YouTube released their own figures which also include global totals.

This news is thought to calm a few analysts' concerns. First, that YouTube's push to compete with Hulu would create major bandwidth issues.

Second, that even after being acquired by Google for $1.65 billion, the site has been unable to monetize with advertising in any meaningful way.
