If you've been watching any television recently, you've surely seen the barrage of ad spots for Google Chrome, Google Plus, and Internet Explorer 9. I understand Google's effort but am generally confused by advertising specifically for IE9... which can't be as effective / meaningful as focusing on Windows Mobile. Anyhow... the point is that Google took to ESPN.com yesterday to cleverly promote Google Plus alongside the NCAA Tournament. It's well done because it's relevant, good looking and ties into the product very well (circles!). Most interesting is how it ties directly into the product - each NCAA team is "followable" on Google+ and there are scheduled Hangouts with analysts, teams, etc.
Really well done and an interesting twist as they try to differentiate from Facebook and Twitter... and the two areas where they can stand out:
Hangouts (the star of the product) and Media / Lists (something Twitter hasn't nailed yet)
