Ever since the NYTimes.com swept away the last remaining boulders of its subscription pay wall (aka Times Select) in mid-September, its traffic has been going through the roof. According to comScore, it gained 7.5 million readers worldwide from the end of August through the end of October (November numbers are not out yet). That is a 64 percent jump (to a total of 19.4 million). Similarly worldwide monthly pageviews surged 52 percent in that time period to 181 million. Other major news outlets like BusinessWeek.com (4.4 million readers in October), the WSJ.com (3.6 million, with a subscriber wall), and Wired.com (3.2 million) saw gains as well during the Fall, but nothing as dramatic as the NYTimes.com.

To put this in perspective, in the month of October alone, the New York Times added 4.9 million readers on the Web. That is more than double the total readership of CNet’s News.com of 2 million, which sadly seems to be one of the few media sites declining in visitors (from 2.5 million in August). News.com’s pageviews have also been flat, at 6 million per month since August. For comparison’s sake, comScore shows TechCrunch (including our sister site CrunchGear) at 8 million monthly pageviews worldwide in October (we surpassed News.com in September), and it shows us catching up in online readers with 1.7 million worldwide in October. Here are the actual worldwide figures from comScore for a variety of news sites:

And just for fun, here is a chart showing pageviews over the past year for Wired.com, News.com, Economist.com, TechCrunch (with CrunchGear), and ZDNet Blogs. TechCrunch is the green line.
