New York—Siemens rolled out two new TV spots in its “Answers” campaign, developed by Ogilvy & Mather, New York, that focus on energy and healthcare. "Unit 9” features Siemens employees at a manufacturing plant in Charlotte, N.C., working on energy-efficient gas turbines. Another spot, “Rosie,” features a young girl getting a scan from a new Siemens scanner that combines MRI and PET imaging. The spots are running during news programming on broadcast and cable networks. The budget was undisclosed.
