New figures from the Radio Advertising Bureau show that UK adspend on the medium jumped 2.5% in 2002 to £563 million ($898m; €829m).
Top spender was the government, pouring £19.9m into radio commercials. In addition, there were big increases from supermarket group J Sainsbury, which raised spend from £2.6m in 2001 to £8.6m, and newspaper giant News International, whose radio outlay more than doubled to £8.4m.
Spend on the medium climbed in every quarter last year, with Q4 finishing strongly on a rate of 4.2%. The survey also found a 14.8% jump in income from radio sponsorship and promotions during 2002.
The full-year 2.5% growth rate tallies with new figures from Nielsen Media Research (see story above).
