When I first saw this commercial, I thought that it was a brilliant marketing campaign:
What better way to sell clothes to the youth of today then to cater to their parents - the same demographic sought after to buy tickets to see the original 1985 movie, and the same people (presumably) paying for the clothes!
Think about it - in 1985, a fifteen-year-old would have been born around 1970. That would make them 38 now. 38 year-olds with 12-17 year old kids? PERFECT.
Of course, the other interpretation is that JCPenney is just trying to corner the 90s youth market with a staple of 70s television (I know, it should be the "aughts" and "eighties" movies, but that doesn't flow very well, now does it? Snoochie Boochies!).
Either way, I wonder how it's working. I wouldn't know how to check - Penney's isn't my store of choice by any means.
Whatever. Bravo, marketing department!
