COPENHAGEN, Denmark -- Danish toy maker Lego says sales soared 13 percent during the first six months of 2013, thanks partly to the new "Lego Friends" series of building blocks designed for girls.

The privately owned company said Thursday that it made a net profit of 2.4 billion kroner ($424 million) on revenue of 10.4 billion kroner ($1.8 billion).

Lego said series like "Legends of Chima" and "Lego Friends" were among the most popular and that sales were particularly high in Asia.

Lego's other toy series include "Star Wars" and "Ninjago." Last month the company said it will launch a special series themed on the American sitcom "The Simpsons" next year.

The company is not publicly listed but has published earning reports since 1997. It does not release quarterly figures.

  • Tickle Me Elmo

    The popularity of the toy led to a human <a href=",,20143226,00.html">stampede</a> at a Walmart in Canada back in 1996. Pretty sure no amount of cute is worth that much.

    Gak is gross. It's basically a ploy to get kids to stop playing with their boogers.

  • Furby

    Did anyone <em>not</em> lock their Furby in a closet after it wouldn't shut up for over a week?

  • Bop It

    Bop It was made for kids who wished they had an older brother. It's loud, obnoxious and orders you around.

    People collected hundreds of these cardboard circles, allegedly to play some kind of game. Never has anyone in the history of the world played that game.

  • Tamagotchi

    Parents who refused to get their kids a puppy said Tamagotchis were JUST like pets. Turns out they're more like boring pieces of plastic. Live and learn.

  • Polly Pocket

    If your dad wasn't stepping on enough Legos with his bare feet, you could plant some of these babies in the living room carpet.

    The only thing crazy about Crazy Bones is that people paid money for them!

    Basically just a synthetic hair ball.

  • Pokemon

    Pokemon taught children to walk around the forrest and capture wild animals. Not a great hobby for a second grader.
