"iPhone" was the top search term on Yahoo during 2011, the company has announced. Most of the top 10 list consists of celebrities, the second- and third-place spots in fact belonging to Casey Anthony and Kim Kardashian. Yahoo remarks that a piece of electronics hasn't dominated the list since 2002, when Sony's PlayStation 2 occupied the top spot. The last technology-related term to peak was filesharing service KaZaA in 2003.
