Product Life Cycle Management
  
Products are born, they get love from the heat-seeking early adopters, they scale to become a mass media Thing, and then they slowly die, throwing off mountains of cash as everyone knows about them, companies don't need to advertise their existence, and the product fades into oblivion.
If you have a Wayback Machine, look up Blackberry, the ancient cell phone that no longer really exists. The iPhone killed it (along with management's own stupidly conservative ethos). And yes, some day the iPhone will be dinner as well.
What's new? What's hot today? It'll be mass media darling food some day. And then die. The circle of life.
