When I heard about the video it is the apk for video calling. That many of the big was not serious about this concept. But after some period of time the all the large companies get understand how the vidoe conferencing or video call system is too important. At that time bigo live is also paltform was very well know to all. But after launching some big companies there video calling tools. The bigo get taught to survive in the compitition. Also the big companies also invest there money in this tool. Which was largely used by the people. After some bigo not able upgarde there apk so they got out from the compitition. all the others gave some better user interface as campare to bigo. Thank you.
