UPDATED: This has been a long-rumored possibility for the tech blog started in 2007 and run by co-executive editors Kara Swisher and Walt Mossberg. Fortune first reported that the separation would come at year’s end, when the current partnership agreement expires. News Corp subsidiary Dow Jones would keep the AllThingsD brand and Mossberg will leave behind his Wall Street Journal tech column after being at the paper forever, fellow Dow Jones property WSJ reports. Fortune says potential new investors include NBCUniversal, Bloomberg, Conde Nast, Cox and The Washington Post, which was just acquired by Amazon’s Jeff Bezos, a regular on AllThingsD’s digital pages. It also says a formal announcement from AllThingsD is expected later today, so stay tuned. Dow Jones editor-in-chief and WSJ managing editor Gerard Baker said the paper is expanding its technology coverage and conference franchise overseas, and the plan is to build a new digital home for tech coverage “including the addition of 20 reviewers, bloggers, visual journalists, editors and reporters covering digital”.
