patentpundit writes "On April 18, 2008, Apple Computer applied for a patent relating to an 'invention' that allows for showing advertisements within an operating system. The first named inventor on the patent application is none other than Steve Jobs. The patent application published and became available for public inspection on October 22, 2009. If implemented, the invention would make it possible for advertisements to be displayed on a variety of devices, including desktop computers, cell phones, PDAs, and more. In one alarming aspect, the device could be disabled while the advertisements run, thereby forcing users to let the advertisement run its course before the system would unlock and allow further use. In an even more invasive scenario, explained in the patent application, the user could be required to do something, such as click to continue, in order to verify that they are actively watching the advertisement and haven't simply walked away while the ad runs. Whether Apple would implement such an invention is unknown, but it is possible that they think there are others out there who might want to implement such invasive advertising. It is possible Apple wanted to get ahead of the curve and file this patent so that if any company is silly enough to engage in Big Brother advertising, then Apple will get a royalty. I sure hope this is not the future of advertising."
