Keurig Dr Pepper sells coffee under the Keurig single-serve pod system alongside a portfolio of carbonated soft drinks including Dr Pepper, 7Up and Snapple, combining a beverage company with a coffee brewing hardware and pod business. The Keurig system's single-serve pod format created a recurring, razor-and-blades style revenue stream, where the coffee machines themselves are a smaller part of the business compared to the ongoing sales of the pods those machines require. The company was formed through the merger of the beverage company Dr Pepper Snapple Group and Keurig Green Mountain, combining traditional soft drink brands with the newer coffee pod business. Keurig Dr Pepper's growth depends both on expanding its beverage brand portfolio and defending its coffee pod market position against private-label and competing pod manufacturers now that key original patents on the Keurig system have expired.
