And now, a word from our sponsor. True story: last year, Apple filed for a patent on technology that would force you to watch advertisements, no matter how hard you tried to avoid it.
The idea is that phones, computers, set-top boxes and so on can be sold more cheaply - or even given away for free - if subsidised by adverts. But because nearly everyone who doesn't work in the ad industry loathes advertising, the subsidisers need to ensure people are actually watching these horrid things.
"Its distinctive feature is a design that doesn't simply invite a user to pay attention to an ad - it also compels attention," writes Stross.
"The technology can freeze the device until the user clicks a button or answers a test question to demonstrate that he or she has dutifully noticed the commercial message. Because this technology would be embedded in the innermost core of the device, the ads could appear on the screen at any time, no matter what one is doing."
In this scheme, once an ad starts running, you'll have to interact with it to prove you've watched it. Worse, the interaction will vary - the required activity or location of the "clickspot" will change from ad to ad - which makes them much harder to avoid.
Macworld's Jeff Porten writes: "Forget about having a third-party developer providing you with an AppleScript to bypass this. Unless the advertisement 'counts', you'll be locked out of using the device until you can prove you've paid attention.
"Apple even provides a sample menu bar, which will be haunting my dreams thanks to its Lucida Grande font and obvious Mac integration. This menu allows for the user to 'preload' the timer of how long they can use their device without interruption - by watching multiple advertisements in advance."
This is, of course, a terrible idea. On the other hand, it's not all that alien to readers of the many sites that run full-screen interstitial ads prior to displaying content.
OK, a quick show of hands: how many people actually wait the 15 seconds for the ad to display before clicking that little box with the X or the 'skip this ad' link in the top right corner? I don't think I've ever watched more than 3 seconds of one of those ads in my life, and that was still 2 seconds too many.
The difference is that these ads will theoretically appear on iPhones and TVs as well as computers, and they won't go away by themselves.
