Since its earliest days, the Portal line has been plagued by one major question: why? Not so much why did Facebook make it (for that I give you the following: $$$), but rather, why should people be interested, given Amazon and Google’s respective head starts in both the smart assistant and display categories?

In addition to its integration with Facebook services, Portal’s original standout feature was smart panning, which used object detection to reframe its subjects. It was a clever addition — if not necessarily enough to justify purchasing a Facebook-produced product over the competition. Since then, however, Google, Amazon and even Apple have introduced their own versions of the technology, removing Facebook’s edge.
