Another way of measuring the cost of elections

Not-so-fun fact from the Orlando Sentinel:
"This year's gubernatorial election was the most expensive in Florida history. Over the two-month general election campaign, Republican Rick Scott and Democrat Alex Sink together spent more than $55 million on ads, subjecting the average Orlando TV viewer to their commercials 309 times – equal to two hours and 34 minutes, or roughly the length of the movie 'Avatar.'"
