SAN FRANCISCO ( TheStreet) -- Apple's ( AAPL) iPad has beaten Google's ( GOOG) Android operating system, not to mention teen heart-throb Justin Bieber, in Twitter's list of 2010's top trends. The iPad and Android clinched the fifth and sixth spots, respectively, in Twitter's end-of-year list, just ahead of "Justin Bieber" and the movie Harry Potter and the Deathly Hallows. "Gulf Oil Spill" was the most popular trend on Twitter this year, followed by "Fifa World Cup," the movie Inception, "Haiti Earthquake" and "Vuvuzela," the cacophonous horn that became the symbol of this summer's World Cup.
Apple, which launched both the iPad and the new iPhone 4 this year, also dominated Twitter's list of technology trends, with four listings in the top 10. The tech giant's iPad came in at No. 1, followed by Android, although iOS, iPhone and MacBook Air all featured on the list. Google Instant, a search enhancement that was launched in September, came in at No. 10. 2011 is already shaping up to be a big year for Apple, and the Cupertino, Calif.-based firm is expected to unveil a new version of the iPad. Launched amid great fanfare earlier this year, the iPad has left tablet rivals such as H-P ( HPQ) and Dell ( DELL) in its wake. Canaccord Genuity expects Apple to sell just under 14 million iPads this year, a figure that could leap to just under 27 million in 2011. There have, however, been signs that Android is gaining momentum in the U.S. smartphone market. Canalys, for example, recently reported that Android-based smartphones accounted for almost 44% of U.S. smartphone sales during the third quarter, up from 34% in the prior quarter. Apple shares rose $4.05, or 1.26%, to $324.61 in pre-market trading on Monday. Google's stock was also heading northward, climbing $5.95, or 1%, to $598.16. --Written by James Rogers in New York. >To follow the writer on Twitter, go to http://twitter.com/jamesjrogers. >To submit a news tip, send an email to: email@example.com
