Viacom sees ad growth slowing in 2nd quarter

NEW YORK (Reuters) - Viacom Inc (VIAb.N) expects a slower rate of U.S. advertising growth in the second quarter than in the first quarter, Chief Executive Philippe Dauman said on Wednesday.

The company's second-quarter domestic advertising revenue is expected to grow 3 percent to 4 percent, he said. Viacom's domestic ad revenue rose 7 percent in the first quarter.

"Right now, we're in an economically uncertain environment," Dauman said at the Bernstein Strategic Decisions conference. "We're preparing for that."
