[corporate website]. The DOJ wants to know more about the competitive landscape for multimedia content tools [CNET report]. Adobe makes popular document editing software such as Photoshop, Pagemaker, and Acrobat. Macromedia is perhaps best known for its Flash software, used to create animation-driven content. The request will extend the waiting period [MSNBC report] for the sale to be approved, but both companies expect it to go through by the fall. AP has more.
