Illegalsigns.ca have been keeping track of those Audi TT steel signs that have appeared all over Toronto - long story short, the TT signs are meant to be “set dressing” for an Audi TV commercial so the Film and Televison Office gave the go-ahead. But the press about the ad campaign mention no commercial, instead the TT signs are the ad campaign.
Some liken these signs to street spam, others seem to think that Audi can get away with this if they just send an intern out with a camera to shoot the TT's. Maverick PR and Lowe Roche advertising are getting angry emails from pissed off Toronto people, and the story has even hit boing boing who say: "Audi defrauds Toronto with fake film permits". Not sure that was 'the buzz' they were aiming for... but you never know in this day and age - everyone is talking about Audi now.
