and a breakthrough business model. In 2002, Keurig sold 10,000 commercial brewers. Consumer demand for a home-use brewer version increased, but manufacturing a model small enough to fit on a kitchen counter, and making them inexpensively enough to be affordable to consumers, took time. Office models were profitable because the profits came from the high-margin K-Cups, and one office might go through up to hundreds of those a day. By 2004, Keurig had a prototype ready for home use, but so did large corporate competitors like Salton, Sara Lee, and Procter & Gamble, which introduced their own single-serve brewers and pods. Keurig capitalized on the increased awareness of the concept, and sent representatives into stores to do live demonstrations of its B100 home brewer and give out free samples. Keurig and K-Cups quickly became the dominant brand of home brewers and single-serve pods. Acquisition by Green Mountain Coffee Roasters In 2006, the publicly traded Vermont-based specialty-coffee company Green Mountain Coffee Roasters (GMCR) – which had successively invested in and acquired increasing percentage ownership of Keurig in 1993, 1996, and 2003, by which time it had a 43% ownership – completed its full acquisition of Keurig. Green Mountain also acquired the four additional Keurig licensees, Tully's Coffee, Timothy's World Coffee, Diedrich Coffee, and Van Houtte, in 2009 and 2010. The joining of Keurig and Green Mountain combined a highly technological brewing-machine manufacturer and a nationwide high-end coffee provider into one company, and created an effective "razor/razorblade" model that allowed for explosive growth and high profits. By 2008, K-Cup pods became available for sale in supermarkets across the U.S. Coffee pod machine sales overall multiplied more than six-fold over the six years from 2008 to 2014. In 2010, Keurig and K-Cup sales topped $1.2billion. The high-margin profits from K-Cup pods are the bulk of the company's income; for fiscal year 2014, Keurig generated $822.3 million in sales from brewers and accessories, while the pods had $3.6 billion in sales. In February 2011, Green Mountain announced an agreement with Dunkin' Donuts to make Dunkin’ Donuts coffee available in single-serve K-Cup pods for use with Keurig Single-Cup Brewers. In addition, participating Dunkin’ Donuts restaurants on occasion offer Keurig Single-Cup Brewers for sale. In March 2011, Green Mountain Coffee and Starbucks announced a similar deal whereby Starbucks would sell its coffee and tea in Keurig single-serve pods, and would in return sell Keurig machines in
