Is Worst Behind Us? Online Ad Revenue Up in Q4
With Time Warner reporting earnings yesterday, we now have online advertising numbers for the fourth quarter from the four largest players: Google, Yahoo, Microsoft, and AOL. Tallying up their online advertising revenues provides a decent proxy for the health of the overall online advertising industry as a whole, since they represent a majority of those revenues. (For comparison, see IAB numbers for the U.S. only). After a full year of slowing growth, their combined ad revenues actually picked up in the fourth quarter, showing a 3% rise compared to the third quarter. Combined revenues grew 8% on an annual basis.
