The Institute of Advertising Practitioners in Ireland (IAPI) has produced a guide to media trends over the past five years detailing the inflation being experienced by the five main media.

Television, predictably, fared the worst - from an advertiser's point of view - with a cost-per-thousand inflation of 52 per cent. Morning newspapers experienced the lowest level of inflation at 17 per cent.

Mr Jake Norman of MCM did the number-crunching for IAPI.
