Discovery channel is provide knowledge about all living and non living things in nature.
they also provides documentary television programming, technology and history and recently his expanded into reality and pseudo scientific entertainment .
on this channel playing program is shark week, deadliest catch, cash cab and man vs wild.
my favourite is man vs wild, I have watched this program past two years.
I like this channel because of this reasons.
I also watch drives to savor in sonoma on national geography channel its all about green hills, blue water, state park in sonoma it is similar to discovery channels programs
