History tv 18 is a good knowledge gaining channel. There are somany varity of shows which gives us knowledge of all over which the books cannot.
Ther are somany shows which I like as we can say Pawn Stars, Kings of Restoration, Baggage Battle, The Universe, etc. Pawn Stars is a good show. It gives us the knowledge of old and ancient or war time things which we never knew. And Kings of Restoration is the best show. So, all in all its a good channel.
