Lots of programming on C band,but it depends on what you are interested in.I am assuming you are in the USA?
First, there are tons of Spanish language channels,a few of which have English secondary audio.I receive 500 or more Spanish channels on my 10 ft dish, covering 55W to 127W only.There are a few more Sats to either extreme that I can't reach yet
As for English channels,I get maybe 150 channels.(Not counting channels that I have removed due to lack of interest) Many are channels that one can get with an Over-The-Air antenna
IF they live near a large metropolitan area.Grit TV,MeTV,Ion,Movies,Network affiliates,etc.A few foreign channels from Japan,China,Russia that are in English.Some religious channels and some shopping channels as well.That's not to mention the occasional feeds that open up from time to time.
There are some radio channels if you are interested in that.
Do NOT expect to get HBO, Cinemax,or other premium channels.There are occasional premium channels that unscramble temporarily...but they are rare and not something you can depend on.We do not discuss those here in open forum.
There are few channels with languages other than English or Spanish.Unlike KU which has so many foreign languages that I have no interest in.
I can always find something worth watching on C Band.
You will want a dbs-2 receiver with HD capability if possible.Analog is gone and dbs channels are moving toward dbs-2.
That is just a brief description.There are members here who can address any more complicated question you may have.Good Luck!
