HTC has come a long way since '97, when it was working on touch-based Windows CE devices. Over the last 15 years, the company has released many new technologies and new devices, including the Compaq iPAQ and a variety of other popular Pocket PCs. It released the world's first 3G Windows Mobile smartphone. The first commercially-available Android phone. The first Nexus phone (which, sadly, didn't make the cut in the video). In short, HTC has done a lot for the mobile industry, and it has released a video showing off a few of these things.
Of course, it all leads up to the crème de la crème: the HTC One.
