Clearwire was formed in late 2008 via the merger of the old Clearwire, a business founded in 2003, and Sprint Nextel's WiMAX business, which included wireless spectrum and network assets. Several firms invested $3.2 billion in Clearwire at its formation, including Google GOOG, Comcast CMCSK, and Intel INTC. The firm currently operates networks that reach markets with a combined population of about 135 million people. As of September 30, 2011, Clearwire served 1.3 million retail and 8.2 million wholesale customers, primarily via Sprint.
