Agency giants Omnicom and Interpublic are backing a scheme to send 200,000 free PCs to UK consumers in exchange for them viewing a "TV-style" ad every 20 minutes.
The venture is the brainchild of Metronomy chief executive John Thornhill and is to be financed by travel agency mogul Terry Fisher, a former director of Huddersfield Town Football Club.
Punters will have to view the ads for one minute, every 20 minutes, while using the computer.
If the ads aren't viewed the PC is automatically disabled.
There will be a 60-second warning before the ads appear in order to allow people to save work or pause any game they may be playing at the time.
