In July 2005, Google acquired Android Inc.
for at least $50 million, whose key employees, including
Rubin, Miner and White, stayed at the company after the acquisition. [11][13] Not much was known about
Android Inc. at the time, but many assumed that Google was planning to enter the mobile phone
market with this move.[13] At Google, the team led by Rubin developed a mobile device platform
powered by the Linux kernel. Google marketed the platform to handset makers and carriers on the
promise of providing a flexible, upgradable system. Google had lined up a series of hardware
component and software partners and signaled to carriers that it was open to various degrees of
cooperation on their part.[30][31][32]
Speculation about Google's intention to enter the mobile communications market continued to build
through December 2006.[33] An earlier prototype codenamed "Sooner" had a closer resemblance to
a BlackBerry phone, with no touchscreen, and a physical, QWERTY keyboard, but was later reengineered to support a touchscreen, to compete with other announced devices such as the
2006 LG Prada and 2007 Apple iPhone.[34][35] In September 2007, InformationWeek covered
an Evalueserve study reporting that Google had filed several patent applications in the area of
mobile telephony.[36][37]
