How to call a fact when someone copies someone else's idea. Like Microsoft makes Zune after apple's iPod. Like movie Transmorphers after Transformers And so on. Is this a ripoff? sampling? Or what can someone suggest.
Yea i thought too, but urbandictionary.com says ripping off is scamming, this is not exactly scamming.
my teacher in my primary school said to me : ----to a successful person, you should copy your friends work and enhance it to make it better----
The closest thing that I could think of would be, monopolistic competiton. http://en.wikipedia.org/wiki/Monopolistic_competition
