SAN FRANCISCO — Death, devices and celebrity drove the quest for more information on Google's search engine this year.
Three of the world's four fastest-rising search requests on Google were triggered by the deaths of famous men.
Former South African President Nelson Mandela, who died earlier this month, occupied the top spot, followed by "Fast & Furious" movie star Paul Walker, who died in a Nov. 30 car crash. "Glee" TV series cast member Cory Monteith, who died of a drug overdose in July, ranked fourth in an annual retrospective released Tuesday.
The Boston Marathon bombings in April that killed three people ranked sixth.
The iPhone 5S, the latest upgrade in Apple's most popular product line, finished third in Google's rankings. A rival smartphone, the Samsung Galaxy S4, took the eighth spot. PlayStation 4, Sony Corp.'s newest video game console, held the ninth position.
The Top 10 was rounded out by the "Harlem Shake," a song that inspired a procession of amusing dance videos, at No. 5; "royal baby" Prince George, the heir to England's throne, at No. 7; and North Korea, whose saber-rattling has become a source of international tension, at No. 10.
Google's review follows annual round-ups compiled during the previous two weeks by its main search rivals — Microsoft Corp.'s Bing, Yahoo Inc. and Ask.com. Although its list usually comes last each year, Google's breakdown typically provides the greatest insight into the world's collective mindset because the company's technology processes about two out of every three search requests made on the Internet.
Bing ranks a distant second with 18 percent of the U.S. search market, and even less in most other countries. Yahoo, which relies on Bing's technology, handles the third most search requests.
Because the same inquiries tend to crop up from one year to the next, Google tries to keep its list fresh by focusing on the queries that post the biggest annual gains — a measurement that the Mountain View, Calif., company calls "trending."
Google also is slicing its vast database of search requests into a hodgepodge of other categories spanning 72 countries, up from 55 last year. In the U.S. alone, Google is compiling more than 90 different lists examining the hottest inquiries about everything from finances to pop culture.
A handful of the rankings are based on the total number of requests entered into Google's search engine, instead of breaking them down by the variance from last year.
Google's pecking order of the most-searched people in the U.S. consists exclusively of singers, with the exception of reality-TV show star Kim Kardashian, who is engaged to be married to one of her peers on the list, hip-hop artist Kanye West (she ranks No. 3, while he came in at No. 10). The top spot is held by Miley Cyrus, who also was No. 1 in Yahoo's search rankings for this year (Kardashian ranked second on Yahoo's list).
Cyrus, Kardashian and Justin Bieber were the only three people to appear in each of the most-searched lists from Google, Bing and Yahoo. The lists of most-searched people on Google and Bing shared the most in common, with six stars appearing in both categories. Beside Cyrus, Kardashian and Bieber, the other three to make the cut on both Google and Bing were Beyonce Knowles (No. 1 on Bing, No. 5 on Google); Rihanna (No. 3 on Bing, No. 6 on Google); and Taylor Swift (No. 4 on Bing, No. 7 on Google).
