It is ironic that Google launched TV search yesterday, because I was thinking about where search will go, and I think it will follow a similar pattern to television.
When I was growing up, we only had 2 channels until I was about 12 or 13. This was because, in my home town, we didn't have cable TV. But then, we got cable and we got 13 channels.
I was amazed. My TV universe was opened up to much more available programming, all because of a simple piece of cable.
Fast forward to the present and the advent of satellite TV where I have Direct-to-home satellite and have access to over 400 digital quality channels. Almost 25 times more channels than the 13 we had on cable, and over 150 times more than the 2 channels I grew up with.
