This just in from Mashable:

"Though the print and radio industries have both suffered from the rising popularity of online advertising, one industry remains immune: television. U.S. advertisers are expected to increase their spending on TV this year by nearly $2 billion to $66.35 billion, according to forecasts from e-Marketer. By 2017, that number is expected to reach $75 billion, an increase of 14% over five years. At that rate, it will be some time before digital ad spending surpasses TV in the U.S., though it's expected to grow at a much faster rate (over the next five years, 18%)."
