What companies you think could grow if they would use Blue ocean strategy?

Most of them if they have the will to innovate. Blue Ocean Strategy means finding an emerging technology (LEDs/Smartphones/IoT) and then finding a market that would like to use that technology, but can for some reason. Make it so they can use it and there is a market that you own until someone else sees how well you are doing. Downside is that if your get it wrong, it might cost you your company.

For me, Blue Ocean Strategy is not a strategy because it sounds pretty unrealistic. "Find some places where there is no competitors" is always the best choice for any companies, and that is the thing makes this action become unreal. It is just like "winning a lottery" is not a realistic strategy to "be rich".
