NEW YORK: Profits at US media giant Viacom have been boosted by its cable television unit and robust DVD sales. Net income rose 16% year-on-year to $559.5 million (€368.6m; £282m), while revenue climbed 19% to $4.25 billion.

Viacom's domestic ad revenues increased 7%, and 20% in international markets - boosted mainly by the UK and Germany. International sales rose 11%.

Ceo Philippe Dauman (pictured) says the company has benefited from improved ratings at its flagship network MTV and  from a continued shift of ad dollars from traditional TV to cable.

He adds: "To date, the slowdown in the economy has not affected our ad sales."
