We’re often asked how organizations can measure the return on investment from social media. Frank Rich’s column in today’s New York Times effectively uses YouTube views as a proxy for the overall success of the Obama and Clinton campaigns in tapping the power of the web:

The Drudge Report’s link to the YouTube iteration of the CBS News piece [broadcasting Hillary Clinton’s arrival in Bosnia, with no evidence to support her recollection of dodging sniper fire] transformed it into a cultural phenomenon reaching far beyond a third-place network news program’s nightly audience. It had more YouTube views than the inflammatory Wright sermons, more than even the promotional video of Britney Spears making her latest comeback on a TV sitcom. It was as this digital avalanche crashed down that Mrs. Clinton, backed into a corner, started offering the alibi of sleep deprivation and then tried to reignite the racial fires around Mr. Wright.

The Clinton campaign’s cluelessness about the Web has been apparent from the start, and not just in its lagging fund-raising. Witness the canned Hillary Web chats and Hillcasts, the soupy Web contest to choose a campaign song (the winner, an Air Canada advertising jingle sung by Celine Dion, was quickly dumped), and the little-watched electronic national town-hall meeting on the eve of Super Tuesday. Web surfers have rejected these stunts as the old-school infomercials they so blatantly are.

Senator Obama, for all his campaign’s Internet prowess, made his own media mistake by not getting ahead of the inevitable emergence of commercially available Wright videos on both cable TV and the Web. But he got lucky. YouTube videos of a candidate in full tilt or full humiliation, we’re learning, can outdraw videos of a candidate’s fire-breathing pastor. Both the CBS News piece on Mrs. Clinton in Bosnia and the full video of Mr. Obama’s speech on race have drawn more views than the most popular clips of a raging Mr. Wright.
