Abstract: A method of advertizing using a device called Personal Companion. The Personal Companion is a specially designed device or existing Smart Phone linked to cloud based servers via Communication Careers. The device and other enabling gadgets and services are distributed free of charge to members of the public in return for a continuous, uninterruptible flow of consented advertisements. Watching these adverts will typically result in compensation accruing to the user. Users may, however, opt to stop flow of ad, but may forfeit that compensation. The ad server distributes marketing data to the device based on it's physical location, amongst other factors. Preferably, the geographical coordinates of the navigation device are fed to the ad server, which then returns advertisements from businesses operating within those coordinates. The navigation device receives and outputs navigational or entertainment information, in conjunction with marketing data.
