An interesting fact gleaned from a Wall Street Journal piece today on the decision of the nation’s three largest newspaper chains ? Gannett, McClatchy, and Tribune ? to jointly market web space to national advertisers:

During the first nine months of 2006, Internet ad revenues including search ads rose 35 percent to $12.1 billion, according to PricewaterhouseCoopers data compiled for the Interactive Advertising Bureau. During that same period, the local newspaper industry’s ad revenues slipped 4 percent to $17.5 billion, according to TNS Media Intelligence.
