One of my coworkers gave me a tip to check out the numerous podcasts and audio files of top executives speaking about a myriad of business topics. It's called the Educators Corner and it's hosted by the Stanford Technology Ventures Program http://edcorner.stanford.edu/index.html.
One recent video post I found intriguing was by Jeff Housenbold - CEO of Shutterfly called "Creative Direct Marketing." Jeff talks about his time with EBay where he used "Widget" technology to really focus its direct marketing campaign to the exact target customers they wanted. This technology appears to still be in its infancy and really seems very powerful to hone in on your target customers.
Check out the video and the numerous other videos and audio files that you can also download to your ipod on-the-go.
