Google have applied for a patent that relates to their future ability to overlay new ads onto existing poster sites when viewed in their Streetview service. Users could also be able to click through the posters or even buildings, linking them to appropriate websites. Details such as timing, sales mechanic or even likelihood to actually launch have not been confirmed by Google, although unsurprisingly auctions have been mentioned by various parties.
Last year, Google’s Voice technology was used within a campaign promoting the Droid mobile phone. This allowed audiences to leave messages that were displayed on two large screens in Times Square, New York
