Panos Ipeirotis, a professor at NYU's Stern School taught a course over the winter called Search and the New Economy. The website includes useful slides and video-taped lectures. It's enlightening to see how a professor with a technical CS and IR background presents search to a business audience.
You can read more of his interesting work on his blog: A Computer Scientist in Business School. Thanks to Daniel for the pointer to Panos's blog, it's worth reading!
