This equates to a 4 per cent rise in real terms and represents the strongest annual increase since 2000, when the recession was at its worst.
Press accounted for the largest portion of the total spend with a 47.8 per cent share. TV was second (25.8 per cent), followed by direct mail (13.4 per cent). The rest of the share was divided between outdoor (5.4 per cent), radio (3.3 per cent), internet (3.2 per cent) and cinema (1 per cent).
TV expenditure rose by 5.4 per cent to £4.7 billion at current prices, a rise of 4 per cent in real terms. It also accounted for the largest share of display advertising, taking a 33.9 per cent share compared with 31.4 per cent for press.
Outdoor achieved an overall increase of 7.8 per cent to £986 million.
This growth was mirrored by cinema, which delivered a 6.7 per cent rise to £192 million at current prices.
