If you want to innovate on a truly large scale you have to be Apple. Or Samsung. Or Google.
Too many great inventions don’t get adopted because they don’t have a large reach from the git go.
To improve any global existing ecosystem you have to be or become a part of it.
It is impossible to create a better remote for LG TVs and make it a default in every household that has that TV. On your own.
But what you can do is try. And seek out opportunities to sell your invention to the company that can take it to a global scale. Yes, you’ll be letting go of the control over your product, but that’s the only way to improve people’s experiences on a large scale.
