Google Uses Its Home Page to Push Nexus 7 Tablet - NYTimes.com

"I'm feeling plucky" clarification

"Though it is rare, this is not the first time that Google has advertised its products on the valuable ad space of its home page, which 183 million people see every month. It did so for the Nexus S cellphone and the Google Plus social network, for instance, and has used the home page for causes, like directing people to the remembrance of Steven P. Jobs on Apple.com after he died.
For people who use browsers other than Google’s Chrome browser, the company also shows ads for Chrome on the homepage."
