Discovery Channel is my favorite one.Though we are living in 21st century yet we don’t have so much knowledge of species which are shown on this channel.The programme man vs wild is very interesting. This programme is telecasted by ex army man who visits different places and show us different kinds of reptiles, animals etc.Hats off to this person who is doing risky work. Moreover general knowledge programmes are telecasted for example knowledge given by doctors, scientists etc.The stories of brave persons are also told.I have acquired a lot of knowledge from this channel.This is an inspirational channel which motivates us to do adventurous work
