That's what TechPresident has calculated is the value of Obama's YouTube time.

This comes from getting Tube Mogul to work out how many views X length of video he's had — Obama 14,548,809.05 hours; McCain 488,093.01 hours.

Then get Joe Trippi to pass that number through a blender:

Math works like this. The City of Denver has 1.3million TV households -- to buy those households costs $350 per point ($350 to reach one percent of those households) to reach 100% of those 1.3 million for 30 seconds would cost $35,000. So to reach them all for an hour would be 120 X $35,000 = $4,200,000. To get to 14.5 viewing hours you multiply $4,200,000 X 14.5 = $60,900,000.

Now to take out the 300,000 of the 1.3million to get this really down to 14.5 million hours. 300,000 is 23% of 1.3 million -- so we reduce $60,900,000 by 23% = $46,893,000. We could have gotten rid of the 300,000 using the same method at the beginning to make this easier to understand -- but it is going to be around $46 million.

And that's just his campaign's own 1650 videos. Doesn't count will.i.am or any of the rest.

Plus this is pull media not push.

Those are huge numbers.
