Majesco has announced that its Cooking Mama franchise has sold a combined 4 million units in the United States.

According to the publisher, combined sales of the five titles in the Cooking Mama franchise reached the 4 million milestone in less than three years, starting with the original Cooking Mama on the Nintendo DS.

"We are thrilled to reach this significant milestone," said Majesco CEO Jesse Sutton. "Majesco's number one franchise continues to resonate with gamers of all ages and genders."

Follow-up titles to the original Cooking Mama, originally released September of 2006, include Cooking Mama: Cook Off and Cooking Mama World Kitchen for the Wii, and two additional DS titles, Cooking Mama 2: Dinner with Friends and Gardening Mama. Each of these games was developed by Cooking Mama Limited, originally known as Office Create prior to the series' success.

The franchise generated 1.6 million sales as of January 2008, a number that has more than doubled since that time.

"We will continue to explore ways to expand the Mama brand with innovative and compelling products that offer new entertainment experiences," said Sutton.
