Looking back, Android's existence has been a blur. It's now a historically big operating system. Almost a billion total devices have been sold, and 1.5 million devices are activated per day—but how did Google get here? With this level of scale and success, you would think there would be tons of coverage of Android’s rise from zero to hero. However, there just isn’t. Android wasn’t very popular in the early days, and until Android 4.0, screenshots could only be taken with the developer kit. These two factors mean you aren’t going to find a lot of images or information out there about the early versions of Android.
The problem now with the lack of early coverage is that early versions of Android are dying. While something like Windows 1.0 will be around forever—just grab an old computer and install it—Android could be considered the first cloud-based operating system. Many features are heavily reliant on Google’s servers to function. With fewer and fewer people using old versions of Android, those servers are being shut down. And when a cloud-reliant app has its server support shut off, it will never work again—the app crashes and displays a blank screen, or it just refuses to start.
Thanks to this “cloud rot," an Android retrospective won’t be possible in a few years.
