Censorship on MTV

Censorship on MTV has been the subject of debate for years. MTV, the first and most popular music television network in the U.S., has come under criticism for alleged censorship in their programming. Throughout the decades, MTV has altered or removed shows from the channel's schedule to address complaints; and music videos have been censored, moved to late-night rotation, or banned from the channel's rotation for various types of controversial content.
Censorship in full-length programming.
The hit show "Jackass" was subject to frequent censorship in the early 2000s. The popularity of the show, combined with the propensity of young viewers to attempt to imitate the show's risky stunts, led to substantial controversy. Although the show featured prominent warning messages at its start, end, and upon return from all commercial breaks urging viewers not to re-create any stunts seen on the program, nor submit footage to the network of those stunts for casting consideration on that or other MTV series, the show was nonetheless blamed for many injuries. In 2001, then-Senator Joe Lieberman urged Viacom to take more responsibility for the program's content; which led MTV to only air the show after 10p.m. The creators of "Jackass" expressed frustration over the restraints that MTV's producers imposed on stunts after Lieberman's statement. These limitations eventually led to the departure of several cast members, and to the conclusion of the show. 
MTV's influence also affected its famous animated program, "Beavis and Butt-Head". In the wake of a controversy that followed a child burning down his house after allegedly watching the show, producers moved the show from its original 7p.m. time slot to a late-night, 11p.m. slot. Beavis' tendency to flick a lighter and chant the word "fire" was removed from new episodes, and controversial scenes were removed from existing episodes before rebroadcast. Some of the edits were so extensive that when series creator Mike Judge compiled his he commented that "some of those episodes may not even exist actually in their original form".
The Parents Television Council has argued that much of the censored material on MTV is easily discernible because of the context in which it is presented.
Censorship of music videos.
MTV has frequently edited music videos to remove lyrical references to drugs, sex, nudity, violence, weapons, homophobia, suicide, religion or advertising, and completely edits out swear words. Usually, all racial slurs are censored on MTV music videos and programming, and MTV has emphasized racial tolerance for people of all races and creeds.
Examples of lyric edits have included:
Videos moved to late-night or obscure rotation.
In attempt to address criticism over risqué content, MTV has sometimes moved certain videos to late-night rotation in censored format. 
Banned music videos.
From MTV in the United States.
Several videos have been perceived as too controversial to play on MTV even in censored form, for varying reasons. In the 1980s, parent-media watchdog groups such as the PMRC criticized MTV over certain music videos that were claimed to have explicit imagery of Satanism. MTV has developed a strict policy refusing to air videos that may depict devil worship or anti-religious bigotry.
