- The first one was proprietary vertical computing represented by mainframe companies like IBM and mini Computer Companies like Digital Equipment. These companies did everything themselves (hardware and system software and some application software). Apple is the only contemporary company that resembles this structure. IBM is still around but mainly a systems integrator. Digital was acquired by Compaq in 1998.
- The second one was the age of the personal computer. It was a horizontal structure where a few companies dominated the various hardware and software layers (Intel had more than 80% of the microprocessor business and close to 100% of the profits while Microsoft had about the same in the OS and dominated some of the application layers with their office products. At one time both Intel and Microsoft were the most valuable companies in the world. Now Wintel, once the most feared force in computing is no longer relevant.
- The third one is network computing and is led by Google although we have to deal with Apple a bit later. In this wave, the value has moved to the network and expanded encroach on the media industries. Much of the value is created by the consumers themselves. Advertising plays a key part in the monetization of this wave.
- The fourth wave will surly come even if I for one can not yet imagine what it is (although I try). And Google and the other companies riding the crest of the networking world will suffer the same faith as their predecessors.
