Can I have a drum roll and a big WE GET IT award for GlaxoSmithKline. The use of a simple and smart domain for a television medical advocacy call-to-action is exactly what domains like this were born to do. I don't see too many spots like this in spite of all the companies holding the great list of domains released by Marchex today.
Sure easier to remember pronounce and sell than GlaxoSmithKline.com or even their smart choice of GSK.com. Bravo!
