Eyre will chair the IAB Leadership Council, made up of members at managing director level or above from the digital heavyweights including AOL, Freeserve, MSN and Yahoo!. The aim is to double the estimated 1 per cent share of advertising revenue that interactive media currently takes.
The former chairman, Danny Meadows-Klue, will retain his role as the chief executive of IAB UK.
Eyre said: "I will have a dual-facing role: within the digital industry there are issues of having a large number of diverse companies jostling for space and they need to deal with the wider market as a coherent medium, not so fragmented."
"But the key will be my outward-looking role, educating and marketing to the advertising industry about digital media. The early throes in the industry were difficult but those that have survived prove it is a very sustainable sector and the advertising industry isn't quite sure what to make of it," he added.
He held the post of chief executive at Capital Radio from 1991 to 1997, from which he helped found the Radio Advertising Bureau, and was also the chief executive at Pearson Television from 2000, until its merger with RTL in 2001.
Eyre also worked for 16 years in the advertising industry, including a role as the media director at Bartle Bogle Hegarty until 1991.
He currently holds a number of non-executive roles including an associate partner at the media communications agency Unity. He is also the chairman of the production company RDF, which makes shows including Wife Swap and Faking It, and has a directorship at the bio-dome centre Eden Project.
