Over the years, Lego has had five strategic initiatives aimed at girls. Some failed because they misapprehended gender differences in how kids play. Others, while modestly profitable, didn’t integrate properly with Lego’s core products. Now, after four years of research, design, and exhaustive testing, Lego believes it has a breakthrough. On Dec. 26 in the U.K. and Jan. 1 in the U.S., Lego will roll out Lego Friends, aimed at girls 5 and up. (French Lego retailers are going rogue and plan to bring out Lego Friends on Dec. 15.) In Lego’s larger markets, like the U.S., Lego determined it was better to introduce the new line after the holidays, when Wal-Mart Stores, for example, would give the line dedicated shelf space it wouldn’t during the holiday sales rush. The company’s confidence is evident in the launch—a full line of 23 different products backed by a $40 million global marketing push. “This is the most significant strategic launch we’ve done in a decade,” says Lego Group Chief Executive Officer Jørgen Vig Knudstorp. “We want to reach the other 50 percent of the world’s children.”

To develop Lego Friends, Knudstorp relaunched the same extensive field research—more cultural anthropology than focus groups—that the company conducted in 2005 and 2006 to restore its brand. It recruited top product designers and sales strategists from within the company, had them join forces with outside consultants, and dispatched them in small teams to shadow girls and interview their families over a period of months in Germany, Korea, the U.K., and the U.S.

The research techniques and findings have been controversial at Lego from the moment it became clear that if the company were serious about appealing to girls, it would have to do something about its boxy minifigure, its 4-centimeter plastic man with swiveling legs, a yellow jug-head, and a painted-on face. “Let’s be honest: Girls hate him,” says Mads Nipper, the executive vice-president for products and markets, Lego’s equivalent of a chief marketing officer. In terms of Lego iconography, the minifigure is second only to the original studded brick. It’s as hallowed as a 1 5/8th-inch piece of plastic can ever be. (via Lego Is for Girls – Businessweek)
