Android
According to a legend, the founder of the company, Andy Rubin, was called android because of how much he loved robots. So when he started working on his own operational system, he chose this name for it.
The Android logo was designed by Irina Blok. She said that she pictured a robot but just couldn’t come up with the right image. It’s funny that the pictures drawn on restroom doors helped her come up with an idea for what she wanted. This is the origin of the green person with antennas on its head.
