Blade Runner for instance. Its neon hazed dystopian future was populated with huge towering Coca Cola, TDK and Atari adverts. Theres no subtlety, but Scott uses the ads as a tool to ground its depiction of the future in reality - with familiar products making the world both alien and alarmingly real. Or theres the superb TV drama Mad Men, which uses a variety of real products as plot specific accounts for the members of Sterling Cooper advertising agency. Then theres those which have poked fun at product placement - most famously a classic scene from Waynes World - in which the whole notion of product placement is poked fun at. Likewise, The Truman Show satirized the notion of product placement in TV and film, with its fictional actors contractually obliged to clunkily promote products live on air, often directly to a confused Truman (Jim Carrey). But its when product placement is so offensively blatant that it has the potential to ruin both the audiences engagement and the credibility of the film itself. Here's just some of the worst offenders, featuring the clumsiest and most shameful product placement of all time.
