Pre-commercial release versions (2007–2008)
Android alpha
There were at least two internal releases inside Google and the OHA before the Android beta was released in November 2007. For the milestones in internal releases, names of fictional robots were chosen, with various releases code-named "Astro Boy", "Bender" and "R2-D2". Dan Morrill created some of the first mascot logos, but the current green Android logo was designed by Irina Blok. The project manager, Ryan Gibson, conceived of the confections naming scheme that has been used for the majority of the public releases, starting with Android 1.5.
Android beta
The Android beta was released on 5 November 2007, while the software development kit (SDK) was released on 12 November 2007. The November 5 date is popularly celebrated as Android's "birthday". Public beta versions of the SDK were released in the following order:
1. 16 November 2007: m3-rc22a
2. 14 December 2007: m3-rc37a
