To celebrate their three decades on the air, PBS’ Nightly Business Report teamed up with Knowledge@Wharton to select the 30 most important innovations from the last 30 years, which can be found on the PBS Site. Without giving everything away, the top 10 were:

10. Non-invasive laser/robotic surgery
  9. Office Software
  8. Fiber Optics
  7. Microprocessors
  6. Magnetic Resonance Imaging
  5. DNA Testing
  4. e-Mail
  3. Mobile Phones
  2. PCs
  1. The Internet

And while #20, social networking via the internet, to borrow a phrase, really grinds my gears, I have to say that the top 10 are dead on.
