The ad led Sprint users to text "scan" to 70734 to get a program called Scanlife that allows such interaction. The ad also contained a barcode which led to a page with some free ringtones. Some phones require you to take a picture of the barcode, which then gets interpreted. Other phones let you simply move the camera over the barcode and as soon as it is recognized (in real-time), the phone beeps and takes the appropriate action.
Scanlife uses their own format, EZcodes, though they also recognize several other popular formats. Depending on the format, many support more than just linking to websites such as storing contact information, SMS and text information, calendar info, call a phone number (no need to dial), etc. For instance you could put a code containing contact information onto your business card, and now someone can easily add all your information to their phone.
Apparently QR codes have become the most popular format in Japan, and they started printing the codes on all sorts of things since at least 2005. Here's the results of a survey that was done in Japan about how often people use QR codes and what for.
And of course, I've created a QR Code for symbii.com which I've put in the footer of the page (also pictured below):
