What's the name of that kind of video with dynamic style, dubbing and animation style introduction, fast and unified? What is it made of?

Ming 'en Media is a media advertising company.

In 211, the company released a video short film "Where is the taxpayer's money? "Everyone is a taxpayer" and "Who moved our CPI? And in 212, such videos as Micro Killer, Official Promotion Timetable, Sorrow London Olympic Organizing Committee, Elite Migration Map, Let Children Go First, Remembering Love, Keeping Love, Seeing Public Welfare Clearly, and Legal Matters were uploaded to major video websites and reprinted by netizens, thus becoming popular on the Internet.

This video is not Ming En's, but it is also in this style. I don't think it was made by PPT.
