It's about creating the new out of the old and winning a niche in the marketplace. Timelessness is the barometer of excellence. Kids still play with hula hoops and frisbees, fads of my youth. And no amount of promotion will bring back the Pet Rock or the Spice Girls. Craft a reason why it is back.
Consumer demand is always a good start.
Hollywood is good at this. Nothing is easier than marketing the second chapter of a movie, like Austin Powers, that is already a hit. But your product or service need not be introduced as the same as its predecessor. It can be the second version. A return to roots.
