Twitter has overtaken Facebook as the most popular social network among US teens, according to a new survey.
The study by the financial firm Piper Jaffray found Twitter was preferred by 26 percent of adolescents while Facebook and its recently acquired unit Instagram were each chosen by 23 percent.
It found that Twitter, Facebook and Instagram remained well ahead of other social networks used by teens.
Just four percent of teens preferred Tumblr, unchanged from earlier this year, and three percent named Google+, down from five percent.
The news comes as Twitter is readying a $1 billion initial public offering, which will be significantly smaller than Facebook’s last year but still among the most coveted in the sector.
Twitter reports having 218 million active users worldwide.
The survey of some 8,600 teens showed a shift from a survey earlier this year in which Facebook was preferred over Twitter by 33 to 30 percent.
The note that Instagram “continues to look like a smart acquisition for Facebook as it is now tied with Facebook as the second most important social network according to our teen survey.”
It noted that a plan to include advertising on the Instagram platform would be “a catalyst” for Facebook, for which Piper Jaffray set a target price of $57 a share.
Facebook shares were down 2.6 percent in morning trade at $45.91.
