Six Apart, creators of Movable Type, today announced that SUP, a Russian media conglomerate, has acquired LiveJournal (LJ), a top blogging/social networking site. SUP has launched an American company, LiveJournal, Inc., to manage and operate LiveJournal globally.

This agreement builds on the established and successful relationship between Six Apart and SUP, which entered into a licensing agreement in October 2006 permitting SUP to manage LiveJournal in Russia. The Russian LiveJournal community is second only to the U.S. in number of accounts, and has been influential enough in that country to make “LiveJournal” synonymous with “blogging” in Russian.

“While we’ll miss being LiveJournal’s home, this is a great milestone for LiveJournal and also lets us to focus on the core products invented at Six Apart: Movable Type, TypePad, and Vox,” said Chris Alden, CEO and Chairman of Six Apart. “We are investing heavily in the products and have substantial growth plans for 2008.”

“We have been impressed by the expertise and enthusiasm that SUP has brought to LiveJournal in Russia. They’ve introduced new features, nearly doubled the number of users, invested in key product enhancements, and have done justice to one of the most innovative online social networks in the world. Judging both by SUP’s track record and their eagerness to create a new user advisory board to oversee the community’s interests, this is clearly a good fit,” said Alden.

“Having gotten to know LiveJournal in Russia over the past year, we see enormous potential in developing the business worldwide; it has already shown its durability in America. We believe this is a great opportunity,” said Andrew Paulson, CEO of SUP.

Six Apart acquired LiveJournal in January 2005 from its founder, Brad Fitzpatrick.

Six Apart will continue its active investment in and promotion of the signature open source platform technologies created by the LiveJournal team, such as Memcached, Mogile, Perlbal, and OpenID, all of which have been adopted by other leading web properties from Craigslist to Facebook to Wikipedia.
