Britain, the world's most developed online advertising market, is on the cusp of making more digital history. Ad spending online will pass print and television next year, says the Internet Advertising Bureau, the World Advertising Research Centre and PriceWaterhouseCoopers. The market share was 15.3 per cent in 2007 (revenues of about $5.6 billion), behind print (19.9) and TV (21.8), but the rapid growth is set to eclipse both media next year. The pace of growth in paid search is slowing somewhat, but search, classified and banner advertising all showed strong growth. The Reuters story on the report is here.
