Business publisher Centaur has announced a 3 per cent drop in revenue in its half-year results but a 4 per cent rise in digital revenue, which now makes up almost a third of its total income.

The company said that underlying growth – which takes into account the impact of discontinued activities, acquisitions and disposals – was up 4 per cent in the first half of its financial year, while underlying earnings were up 39 per cent to £1.6m.

Over the last year the company has sold a number of titles and introduced a restructure that saw the departure of several senior management figures. It also scrapped the print editions of Design Week and New Media Age.
