Ratings for Stern's shows remain healthy

Stern's radio show has been targeted in the wake of Janet Jackson's Super Bowl breast-baring earlier this year.

But Infinity chief operating officer Joel Hollander said: "We're going to support Howard and all of our on-air talent 110 percent."

Stern had said he thought his days at the Viacom-owned company were numbered.

His long-time supporter, Mel Karmazin, quit as Viacom's second-in-command earlier this month.

As well as Infinity, Viacom also owns MTV and US broadcasting giant CBS,

Audiences rise

Mr Hollander's pledge came during a trade convention in Los Angeles.

Stern's syndicated show was dropped by six stations in February for indecency.

But his audience figures went up between January and March in the three biggest US markets - New York, Los Angeles and Chicago.

Stern had blamed his show being dropped on a conservative backlash.

Panellists at the Radio & Records convention had objected to tightened indecency laws in the wake of the Super Bowl incident, in which Janet Jackson's breast was exposed during live TV coverage.
