We've uncovered what's really killing the online-advertising business: Sarah Palin! Or rather, the lack thereof. Traffic at Hulu, NBC's YouTube wannabe, tumbled in November without the Web's favorite hot lady governor and VP candidate.

ComScore, a Web-traffic measurement firm, reports that visitors to Hulu.com dropped 11 percent from October to November, when it only drew 4.8 million viewers. NBC.com dropped by half, from 14.1 million to 7.2 million. Which only makes sense, says Peter Kafka at MediaMemo, since NBC.com and Hulu were the two places where people could see legal copies of Tina Fey's Palin impressions for Saturday Night Live.

Look, I realize Palin has gone back to Juneau to sort through all the clothing the Republican National Committee bought for her. But new media badly needs some star power. Can't we give her her own YouTube channel or something?
