According to Nielsen IAG, the Apple iPod product placement in the September 18 episode of ?Supernatural? ranked number one, in terms of recall among broadcast network product placements.
The iPod product placement in Supernatural was followed by product placements from renowned TV shows ?Chuck? and ?Terminator: The Sarah Connor Chronicles?, which featured the Crown Victoria and the Dodge Ram pickup, respectively.
According to Robert Seidman of TVbytheNumbers, ?This isn?t measuring total exposure of the product placement, rather the percentage of viewers who can recall the product placement within a 24 hour period. The iPod placement in Supernatural was recalled 2.3 times more than the average product placement. Even more than a month after it aired, I remembered the iPod scene in Supernatural.?
