Old-age brands like Britannica have literally been eliminated within a couple of years due to the introduction of the internet. Those are just a few examples Greg Fisher mentions on his presentation entitled 'Managing for Innovation'. Greg goes in depth on how 4 companies P & G, Discovery, Google, and IDEO have managed to raise the bar in innovation with four different management philosophies and four different innovation models. These four companies embody the words 'entrepreneurial spirit'. This presentation is a good refresher on this concept. Enjoy!
