Multigenerational Marketing

There are days when I think that there is really nothing new anymore. If you think about the number conversion of old tv shows into movies for the "new" generation it makes you wonder if people have really run out of good ideas lately.

The latest thing I noticed today is bringing back the horror flick of my past "Nightmare on Elm Street" from 1984 into today's generation of kids. The link on the title just makes me shake my head once again asking when can we get some decent new ideas going? What are the iconic shows/characters/films of today that we'll see 25 years from now? Is it taught in marketing somewhere to look up stuff from a generation ago and see how you can repackage it again for more bucks?
