The Wall Street Journal's highly anticipated Bay Area edition launches tomorrow with coverage of local news folded into the A-section of the paper every Thursday. The corresponding site WSJ.com/SF will aggregate content from other Dow Jones sites and blogs related to the region.

The commitment to new turf comes less than a week after the Journal closed its Boston bureau, and less than three weeks after The New York Times rolled out its Bay edition. Aspects of the Times edition, and corresponding blog are well covered by our sister blog Baynewser.

Some may remember that the Journal published six regional editions for a number of years in the 90s to cover Texas, California, the Pacific Northwest, Florida, New England and the Southeast. All were shuttered in the fall of 2000 as reverberations were being felt in the ad market after the big stock market plummet of the spring. The new Bay area edition, like the California edition of a decade ago create a new revenue stream by offering ad space to local advertisers interested in reaching the readership, at a fraction of the national rate.
