Aka Blue Ocean product/market strategy.

Basically, rather than being a shark swimming in a ocean that is colored red from the blood of all the other sharks competing, you leave and find a blue ocean.

Sounds good on paper but sometimes that market is much smaller, and/or just being the first-to-market doesn't guarantee you'll be successful.
