Youtube is a very big platform to share your own videos as well as to watch others video. There is a lot to gain from youtubes videos. When I need help in solving a problem, I took help from youtube videos. I even learnt basic guiter playing from youtube videos. The very best part of youtube is, it has all the old serials that once aired in Doordarshan like Bikram Betal, Malgudi days, Byomkesh Bakshi etc. Youtube also gives the option to select the video quality to watch videos according to ones need. A must have app.
