Most non sky satellite receivers usually state that they can store up to around 5000 channels.
My latest one says its unlimited so I have no idea how many I can actually get but as you said Clive, a lot of them are rubbish.
I think I only really regularly watch from a choice of around 100 chanels of films and a few 10s of discovery, nat geographic type and a few 10s of news channels.
If I had young kids here then they would have 100s of cartoon channels and if I had a pervy partner hed have access to ridiculous amounts of porn, if I allowed him to watch it
Occassionally I find a few sports channels that show real sports like F1 and Moto GP but mostly they show football, cricket and tennis
