B2B publisher Centaur Media has reported a £5m pre-tax loss despite revenue increasing by 14 per cent to £30.4m in the six months to 31 December.

Figures released today show digital now accounts for 39 per cent of total revenue (up 7 per cent year on year) while print revenue fell from 45 per cent of the total in the last six months of 2011 to 31 per cent.

In July 2012 the company acquired digital marketing company Econsultancy for £12m, and today said it had contributed £4.2m of revenue since its acquisition.
