RootsWeb will otherwise stay the same and stay free, says Sullivan. This move will not change the RootsWeb experience or alter the ease of navigation to or within RootsWeb. RootsWeb will remain a free online experience. Old URLs will work; you wont need to update any bookmarks.
The reason for the change is to get more people to move back and forth between Ancestry.com and RootsWeb. According to the announcement, only 25 percent of visitors to Ancestry.com visited RootsWeb in January 2008, and only 20 percent of visitors to RootsWeb visited Ancestry.com.
The Generations Network (formerly MyFamily.com), which owns Ancestry.com, acquired RootsWeb in June 2000.
