From the Washington Post:

Newsweek magazine, owned by The Washington Post Co. of the District, plans to split its Web site from MSNBC.com to increase control over advertising sales and editorial content. Newsweek's publisher Greg Osberg said the new site would begin in mid-October. Newsweek.com plans to continue sharing content with MSNBC. The new contract with MSNBC replaces a seven-year agreement that expired in June. The Post Co. is investing in its Web sites to attract advertising revenue lost at its flagship newspaper and at Newsweek.
