Google and Yahoo have proposed a revised version of their search advertising partnership to the U.S. Justice Department according to a Wall Street Journal article. The revised proposal limits the amount of revenue Yahoo can receive from the partnership to 25 percent of Yahoo’s search advertising revenue, shortens the length of the partnership to two years from a possible 10, and allows Google advertisers to opt out having their ads appear on Yahoo. The Wall Street Journal also reported that people familiar with discussions between the companies and the Justice Department told them that as of late last week a stalemate had been reached in the discussions.
