AnnArbor.com content will move to the MLive.com online and mobile news platforms on Sept. 12, and AnnArbor.com will shut down after four years as a standalone website. Along with that change, the twice-weekly AnnArbor.com print publication will be rebranded as The Ann Arbor News. The moves were announced Sept. 4 by Dan Gaydou, president of MLive Media Group.
