Is Firebrand.com, the "advertainment" website funded by a multimillion-dollar investment from Microsoft, NBC Universal, and GE, going to be shut down? [UPDATE: Another tipster tells us that Firebrand was shut down yesterday, and that all employees have been told to hand in their Blackberries and not return to the company's headquarters]. [UPDATE 2: An hour and eleven minutes later, the NYT makes it official]. And regarding yesterday's rumor that Saatchi & Saatchi X might get folded into its parent company, the agency's CEO Andy Murray says it isn't true; "This is not the kind of operation you just fold into another agency. A very weird rumor with absolutely no merit," he writes.
