I was impressed today by a display ad that I came across on Yahoo! News for GE.
Rather than show us a nice pretty image and clever tagline, the ad promotes a live web event with GE's CEO Jeff Immelt. What a liked most about the ad is tha when you click on it, it expands to open up a window where you can input your question for Immelt directly from the banner.
The fact that the event is today, makes the ad all the more effective.
