I call this the Spaghetti Cannon strategy.
Load up a cannon with cash and different ideas, blow up the cash and see what sticks to the wall.
If we redrew the corporate boundaries of Google and Microsoft, we'd see them as investment firms tasked with turning a reliable long term cashflows into new reliable long term cashflows. Quasi-venture firms.
So far, Google has advertising. And that's it.
Microsoft have Windows, Office, Server & Tools and Xbox.
So in actual fact, Microsoft are proving that yeah, it sorta works. Sorta.
