Whitney Houston spans the curiosity bounds topping both American and worldwide lists. Duchess of Cambridge Kate Middleton doesn't make it on the U.S. buzz chart but the emergent NBA sensation who spawned "Linsanity" had Americans Googling.
While Google is the most widely used search engine with more than 900,000 unique monthly visitors, other popular ones released their top searches as well, allowing for a point of comparison.
Bing said its top searched person of 2012 was Kim Kardashian, swapping spots with 2011's number one Justin Bieber. Whitney Houston does not appear on the most searched people list but was the site's second most searched musician, behind Bieber.
