I hate sharing bad news about the growth–or lack thereof–of online advertising, but the numbers are, well, the numbers.
TechCrunch has compiled some neat visuals to helps us understand how online ad revenues have slowed among Google, Yahoo, Microsoft, and AOL.

As you can see, Q4 of 2007 enjoyed a growth rate of 12.7%–compared to around 1% in Q3 of this year.
Are you worried?
