Strong Leapster Explorer sales and broader retail distribution contributed to LeapFrog Enterprises boosting net sales by 23% to US$138 million during this year’s third quarter.

The Emeryville, California-based designer, developer and marketer of technology-based learning products also witnessed strong point-of-sale quarterly results attributed to the recent introduction of the Leapster Explorer Mobile Learning System and new product introductions in the company’s learning toy line. Additionally, the Learning Path online community has grown its user base to 4 million, up from approximately 3 million connected consumers at the beginning of the year.

Net sales from the international segment were US$27.2 million for the quarter, also up 23% compared to US$22.1 million a year ago, and were unaffected by changes in foreign currency exchange rates. Income from operations for the quarter was US$16.2 million, an improvement of 79% compared to US$9.1 million a year ago.
