Yellow pages publisher Idearc saw quarterly profit rise 7.8 per cent to $111m (£56m) year on year, thanks to a more web-focused strategy.

The company reported internet revenue of $73m (£37m) in the first quarter, a 7.4 per cent increase over the same period in 2007.

"We remain committed to our multi-product strategy, which we believe will ultimately maximise value to our investors," said acting chief executive Frank Gatto.

The company is looking to expand its internet-based products as shares have fallen 91 per cent over the past year thanks to investor concern over the profitability of traditional print directories.
