In the latest episode of Version History, we look back at why Amazon’s Fire Phone didn’t make it.

Product Feature & Technology - The phone featured "dynamic perspective," considered a key feature by Jeff Bezos, designed to reorient the display based on the user's head movement, creating a 3D effect [1][2] - The phone used four IR projectors, one in each corner of the front, to track the user's position [2] - The 3D effect's functionality was inconsistent, with instances of freezing and mixed user experiences [3] Market Context & Industry Trends - The development of the 3D feature was influenced by the popularity of 3D technology at the time, including the Nintendo 3DS and 3D movies [4] - The viability of 3D technology depended on specific viewing conditions, such as using the right glasses and sitting directly in front of the screen [5] Internal Perspective - The priority given to the 3D feature by Mr Bezos was not surprising given the prevailing trends and interest in 3D technology [5][6]
