Comcast says that 4 percent of its bandwidth goes to YouTube and they say that’s great news.

See also NewTeeVee’s compilation of audience for the new television:
* YouTube: 41.1 percent market share, 86.8 million sessions, 29.7 million unique visitors
* MySpace: 19.3 percent share, 40.9 million sessions, 17.6 million visitors
* Google: 10.2 percent share, 21.6 million sessions, 12.1 million visitors
And so on.

Though it’s comparing apples and kumquats (networks v. shows), note the latest big-TV ratings: 33.9 million for American Idol. But consider also that TV penetration is roughly double broadband penetration, still.
