Five years ago, on 5 November 2007, the newly formed Open Handset Alliance unveiled Android -- an open-source operating system for mobile phones.
Although Google is Android's auteur, 34 corporations including T-Mobile, HTC, Motorola and Qualcomm formed part of the Alliance. The stated goal was "fostering innovation on mobile devices and giving consumers are far better user experience than much of what is available on today's platforms".
