Carat, one of the world's largest media agencies, asserts that online is becoming the third-largest advertising medium this year. It is pulling ahead of radio, even if it remains quite behind television and print media.
Online will hold about 8.6 per cent of world spending, up from 7.3 per cent a year ago. Radio is off only slightly, to 7.4 per cent from 7.5 per cent.
Television has about a 41-per-cent share, while print weighs in at about 36 per cent.
