After the Huffington Post made its own headlines last week when it was acquired by AOL for a reported $315 million, The Nielsen Company analyzed what the Huffington Post’s audience brings to the AOL portfolio in the U.S., specifically among notable demographic groups.

As in December 2010, the same brands were featured amongst the 10 most popular online in the U.S. in January 2011 except for Wikipedia replacing Amazon (now 11th).

According to Nielsen Online, in September NYTimes.com was the top U.S.-based online newspaper site, while MSNBC Digital Network (MSNBC) was the top U.S. online news outlet, Editor & Publisher reported this week.
The NY Times’ website drew just over 20 million unique visitors in September — a 37% increase over unique traffic to the site last September.
