Blogroll is a network of B- and C-list blogs linked from the WashingtonPost.com home page. It launched in August and started carrying advertising in December.
Lufthansa's ads will run across all 100 travel blogs on WaPo's network, including This Non-American Life, LasVegasLogue.com, ParisLogue.com, MoreThanPoints.com, and BaliBlog.com. The placements are standard display ads.
The Sponsored Blogroll program is part of a continuing push into the blogosphere on the part of WashingtonPost.com.
Last month, the site sealed a partnership with politics blog RealClearPolitics.com to provide a daily feed of opinion, commentary, polls and analysis from around the Web.
Ads on the Sponsored Blogroll network are powered by ad serving technology firm Adify's "Build Your Own Network" platform.
