Madonna's Like A Prayer video has been voted the most groundbreaking of all time.

The controversial 1989 promo featured the singer seducing a black Jesus to a backdrop of burning crosses.

It prompted a huge public outcry and was condemned as blasphemous by the Vatican.

Like A Prayer topped an MTV poll to find the top 100 videos that broke the rules.

Madonna features three times in the top five.

Her Ray Of Light video is fourth in the list, with Vogue in fifth place.

Britney Spears is second with her 1999 debut Baby One More Time.

The video of Spears performing a raunchy dance routine dressed in school uniform made her a pop superstar.

Michael Jackson is third with Thriller.

The release of the zombie horror in 1983 was a global news event. Thriller still holds the record for the longest music video ever made.

Jacko's duet with sister Janet on Scream 12 years later - said to be the most expensive music promo in history - is sixth.

MTV commissioned the poll of more than 10,000 viewers to mark the channel's 25th anniversary.

Robbie Williams' Rock DJ, seventh in the list, featured the pop star peeling off his own skin and was deemed so shocking that MTV could only broadcast it in its entirety after the 9pm watershed.
