YouTube、谷歌和Facebook高居2009年青少年热门搜索排行榜之首，不过孩子们关心的问题还不止这些。根据诺顿公司的调查数据，排在热搜榜前五名的其他两个词条是“性”和“色情”。

YouTube, Google, and Facebook topped the list for most-searched terms among kids in 2009, rounding out the top five search terms were "sex" and "porn," according to data from Norton.

The majority of大多数 time spent online for kids 18 and under – or about 30 percent – was spent searching for music-related topics, followed by TV and movies at 12 percent. Not surprisingly, the most popular celebrity名人 search was Michael Jackson, followed by country singer Taylor Swift.

The "Twilight²" series made an appearance on the list. Of the top 100 searches, New Moon came in at number 40, followed by Taylor Lautner at 80, and the New Moon trailer预告片 at 91.

Norton诺顿 collected the data via OnlineFamily.Norton, the free family safety service offered by the company. Between Feb. 2 and Dec. 4, the company tracked 14.6 million searches submitted anonymously³ by users.

Norton said that the appearance of sex-related search terms on its list "should raise a red flag to parents if they haven't had 'The Talk' with their children about content that may not be appropriate for kids."

While YouTube, Google, and Facebook can be entertaining and educational, Norton continued, "parents need to ensure they sit down with their child and talk about what's appropriate and inappropriate when viewing videos online, searching for information on various topics, and interacting on a social networking site."

Broken out by gender⁴, the searches varied⁵ somewhat. YouTube, Google, and Facebook topped the list for both boys and girls, but while "sex" and "porn色情文学" were the number four and five searches for boys, girls searched for "Taylor Swift" or "sex."

By age, YouTube, Google, and Facebook still dominated the top three spots. Among 13 to 18 year-olds, the four and five spots went to "sex" and "MySpace," while kids 8 to 12 searched for "sex" and "Club Penguin⁶." Kids seven and under, meanwhile, looked up "porn" and "Club Penguin."

Other celebrities⁷ that captured kids' attention this year include Miley Cyrus, Lady Gaga, Justin Bieber, Selena Gomez, Lil Wayne, Megan Fox, Eminem, Beyonce, Britney Spears, Demi Lovato, Black Eyed Peas, Jonas Brothers, Rihanna, and Chris Brown.
