What it is:
Game changers are disruptive. They are sometimes crazy ideas. But if they work, they can be wildly lucrative. Unfortunately, they don't come along often.
How it works/Example:
For instance, when Apple introduced the iPod, the product was a game changer. It revolutionized the way in which music was purchased and consumed. Though other companies had already launched MP3 players, Apple's product had a more attractive design, a big marketing budget, and, most important, a music platform (iTunes) that virtually dictated how music would be distributed going forward.
Why it matters:
A game changer is a person or thing that radically changes an industry or a company.
