We all know adverts are a necessary evil, which is why different companies are trying to make them more personalized, more engaging or just plain get rid of them. In a recently granted patent, Sony outlines its ideas for next-gen advertising on network-connected devices -- essentially to make it more interactive. Many of the instructional diagrams involve PS3 accessories in the home setting, but the focus isn't just on adverts as mini-games, which itself is nothing new. Other suggestions for keeping your interest include in-ad purchasing, casting votes or selecting the genre of commercials. To speed up, or get ads off your screen, Sony would have you performing small tasks or -- more sinisterly -- shouting brand names when prompted. Whether such immersive advertising will ever be employed is anyone's guess, but we're sure you're smart enough to know they're just tricks. So who's up for a McDonald's then?
