The league of gentlemen (which i quite enjoy but am just using it as an example) and other bizarre programs were'nt around some time back, and am curious as to why they exist, and what effect they have on our morality, list also includes reality television, especially the live plastic surgery ones

"Bizarre" is a relative term. Each generation of TV watchers has had there own version of "extreme TV", which today would seem tame.

Reason for existence: striving to gain market share.

Effect on morality: if anyone can give me a single convincing reason to demonstrate that Big Brother is morally elevating I'll buy them dinner. Demonstrations of the reverese are unecessary.
