A nice little soundbyte from Steve Rubel at Micropersuasion:

On Sunday YouTube said it hit 100 million video streams per day.

Last week the four TV networks suffered their lowest weekly ratings ever.

Coincidence? I doubt it.

While the numbers don't exactly match up (it's TV's off season, and if you count up all those YouTube viewers watching 3 minute clips, it still doesn't amount to much compared to Network Eyeballs per Hour), it must still be a worrying figure for the Big Four.
