Last month Sony re-launched its AIBO robot dog, which took Mario Munich on a trip down memory lane: It seems not that long ago, in a research project he was involved, that he coded speech recognition and object detection into an AIBO. That was early 2000 before Sony discontinued AIBO in 2006.

Facebook has quietly grown to be a video platform. It has the largest user-generated video content outside YouTube. Each day, people view Facebook videos for 8 billion times and spend 100 million hours watching (with 20 percent of videos live streamed). Facebook users can upload videos, stream live videos on their pages, and have video chats with their friends. Recently, Facebook launched a new feature that lets people do video chat in Facebook Groups.

It looks at the vast landscape, the top of buildings, and the sweeping view of oceans, and captures them for you. In the past five years, the consumer drone market has quietly grown.

The next fact would surprise you (if you are not a drone hobbyist): More than 70 percent of them are made by one single company: DJI.
