Totally agree. What I mean is many research topics can be very interesting from a technical perspective but don't translate into solving problems that are frequent and important enough to build a business around. In the case of Search many business gurus didn't understand at the time that you can make a fortune with a free product. What matters is who has the traffic and who they're selling it to = eyeball meets ad. Page and Brin initially "expected that advertising funded search engines will be inherently biased towards the advertisers and away from the needs of the consumers" (foreshadowing). Also they tried to sell to Yahoo for $1M so it took time to see the full potential, as you describe.
