In the increasing sprawl of this virtual jungle, an overnight network video comes turbulently to us. Especially after the "practical joke on the net" become POP, a gob of online video services are struggling to grow up.
As is well known, the ecumenical video files maybe ASF, WMV played by Media-player, otherwise the RM played by real-player. So this will lead that the different video format needs its correlative player - Bother and for those users whose computer doesn't install the correlative player couldn't watch the videos, in addition these video files are usually in big size, hard to download and not smooth in watching. So the FLV as a new video format, whose full name is flash video, fast speed, smooth watch flow and small file was born.
