Inter-Connectedness of All Things

G4. In 2009, this Website took over as official sponsor of NASCAR driver Bobby Labonte's No. 96 car, seen in the picture (I have blanked out the site name, obviously, wherever it appears on the car). It later also became the official search engine of NASCAR. Rated the No 4 search engine behind Google, Yahoo and Bing, the site uses a natural-language question-and-answer format for its queries. It is owned by InterActive Corp, which also runs the sites Dictionary.com, Thesaurus.com, and Reference.com. Name it.
