PURCHASE, N.Y. - Over the past dozen years, Pepsi has increased the size of its billion-dollar product club two-fold. This year, the soft-drink company announced three new additions: Brisk tea, Diet Mountain Dew and Starbucks ready-to-drink beverages, the Atlanta Journal-Constitution reports.

Each of those beverages now generate yearly sales of more than $1 billion. Now, Pepsi has 22 billion-dollar brands, including some from its food products side. The company has added five products to its billion-dollar sales club since 2007.

"Our ability to accelerate the growth of our billion-dollar brand portfolio with Diet Mountain Dew, Brisk and Starbucks reflects the success of our product marketing and innovation initiatives, the strength of our joint venture partnerships and the power of our distribution systems," said Indra K. Nooyi, Pepsi chairman/CEO, in a statement.

Diet Mountain Dew, launched in 1988, is the eighth carbonated soft drink from Pepsi that has surpassed a billion-dollar-a-year in sales. Brisk, sold under an agreement with Unilever, has grown around 30 percent by volume in this country since 2009. Starbucks ready-to-drink beverages that are in the billion-dollar sales club include Frappuccino and Doubleshot Energy+Coffee.

Pepsi said in a press release that the increase in the number of billion-dollar products demonstrates the company??s focus on expanding its business. The company has struggled with higher costs and slowing demand in the United States, but offset that with higher prices and an increased focus on emerging markets.
