After months of internal negotiation and external speculation, AllThingsD and Dow Jones have decided part ways. According to a statement from Dow Jones EIC and Wall Street Journal managing editor Gerard Baker, the decision was mutual.

Reports picked up on discussions between the two groups early this year, ahead of a partnership contract that’s set to expire on December 31.

AllThingsD co-executive editors Kara Swisher and Walt Mossberg in the meantime began to look for outside investors in the event that negotiations didn’t pan out, securing investment bank Code Advisors to help look for a new partner, Fortune reported.

Interestingly, both Dow Jones and AllThingsD want to expand the tech journalism and event model, but apparently couldn’t agree on a common roadmap.

Swisher told Fortune in August that she and Mossberg are "interested in taking the online journalism and conference efforts we have been successful at building over the last 12 years and expanding them."

Likewise, Baker says in his statement: "We plan to embark on a major global expansion of our technology coverage, which will include adding 20 reviewers, bloggers, visual journalists, editors, and reporters covering digital. As part of this global push, we will also be expanding our conference franchise to include an international technology conference and building a new digital home for our first-class technology news and product reviews on The Wall Street Journal Digital Network."

Fortune also reports that Swisher and Mossberg are still in talks with investors, one of which is said to be NBCUniversal. Others are speculated to be Bloomberg, Condé Nast (Swisher began writing for Vanity Fair in August), Cox Enterprise and The Washington Post Company.

Per terms of the separation, Walt Mossberg will leave the WSJ where he has written the Personal Technology column since 1991.
