Madonna is the artist most associated with music video censorship. The controversy surrounding Madonna's marketing of her sexuality began with the video for "Lucky Star", and amplified over time due to clips such as "Like a Virgin". Outcry occurred over the subject matter (relating to teenage pregnancy) discussed in the video for the song "Papa Don't Preach". "Like a Prayer" courted heavy criticism due to its religious, sexual, and racially oriented imagery. In 1990, Madonna's music video for the song "Justify My Love" was banned by MTV due to its depiction of sadomasochism, homosexuality, cross-dressing, and group sex which generated a media firestorm. In Canada, the debate over the banning of "Justify My Love" by the music video network MuchMusic led to the launching in 1991 of "Too Much 4 Much", a series of occasional, late-night specials (still being aired in the early 2000s) in which videos officially banned by MuchMusic were broadcast, followed by a panel discussion regarding why they were removed.
