The following is a timeline of steps that Motorola has taken so far.
- In April 2010, Motorola co-CEO Sanjay Jha makes the following statement during the Q1 earnings call:
I’ve always felt that owning your OS is important, provided you have an ecosystem, you have all the services and you have an ability and the scale to execute on keeping that OS at the leading edge. And I continue to believe that at some point, if we have all of those attributes, that owning our own OS will be a very important thing. 
- In May 2010, Motorola bought a Linux-based platform called Azingo Mobile . It includes the ability to run web applications on Webkit.

- In March 2011, an article from InformationWeek is titled “Motorola Mobility Building Web-Based OS” and based on a rumor. Quote:
Over the past nine months, Motorola has been hiring engineering talent that would well-suited to create a new mobile operating system. Its team appears to include a significant number of ex-Apple and Adobe personnel, including Gilles Drieu, VP of software engineering at Motorola Mobility, Benoit Marchant, director of engineering at Motorola Mobility, and Sean Kranzberg, also a director of engineering at Motorola Mobility.
- Choosing web technologies: Motorola will have to succeed where Nokia failed. Choosing web technologies for doing so is a smart move, because one avoids reinventing the wheel and there are many developers who already know how to work with such a platform. Palm also made this choice with webOS and it allowed them to catch up remarkably quickly.
- Google and Motorola: Currently, Motorola is selling many Android devices, but Google is not a dependable partner, as they frequently change their allegiance, for example: Motorola (first Android 2 cell phone), HTC (first Nexus One), Samsung (second Nexus One), and Motorola again (first Android Honeycomb tablet). Thus, it makes sense for Motorola to strive for independence. Quote:
“Google is shooting itself in the foot,” said the person familiar with Motorola's plans, citing what he sees as concerns about Android fragmentation, product differentiation, and issues related to Google's support for its partners.
