[i]1. The internet. (The government & Tim Berners-Lee.)

2. Penicillin. “Florey believed it would be inappropriate to patent penicillin, but learned his lesson when some of his American collaborators did just that… Florey took no profit for himself.”

3. AC power & modern electricity. (Tesla)
“Yet Tesla died destitute.”

4. Phone. “Meucci was recognized as the first inventor of the telephone by the US House.” “[He] was unable to raise sufficient funds to pay for the patent application… In 1861 his cottage was auctioned.”

5. Lightbulb. “Göbel [invented] the first practical bulb… in 1854, a quarter of a century before Edison’s patent.”
—http://en.wikipedia.org/wiki/Heinrich_G%C3%B6bel

Yes he died pennyless too.

6. Radio. “Tesla is now credited with inventing modern radio as well; since the Supreme Court overturned Marconi’s patent in 1943 in favor of Tesla’s earlier patents.”

7. Almost everything else - through state funding of science & university research.

The point? While we all love for-profit economics, let’s not exaggerate their role either. At best they tend to succeed after government acceleration of new technologies.
