Below is an old but a very(very…) worthy video where Seth Godin speaks about “Importance of sharing ideas” taking the example of Slice Bread invention.
[Seth Godin on ‘Importance of sharing ideas]
No wonder why “We have so many websites where people can post ideas or pitch online” 
This is an amazing presentation. The way he compares stuff is just awesome.
Cheers,
