LONDON, England (CNN) -- Michael Jackson had a level of hero worship on a par with Elvis Presley or the Beatles but he was the first black star to inspire such a massive following around the world.



Michael Jackson, the ultimate showman, craved attention and was rarely disappointed.



Total worldwide sales of more than 350 million records over his 40-year career give just a hint of the adoration there was for the "King of Pop." The fact that his death came on the eve of a comeback tour in London will leave his devotees feeling even more bereft.



While his career -- and wealth -- had waned greatly in recent years, there was still enough support for the concerts to sell out at a rate of nearly 40,000 an hour. Fans from as far afield as Japan, Germany and Dubai queued to buy their tickets.



Steve Greenberg, founder and CEO of S-Curve Records, was a disc jockey in Tel Aviv, Israel, when "Thriller" first dropped and witnessed first-hand how Jackson became an international icon.



His was a global appeal, Greenberg said, among fans and artists worldwide.



"He was as big in the Middle East and Southeast Asia as he was in America and Europe," Greenberg said. "He had that universality that not many people had. The Beatles had it, Muhammad Ali had it, but not many other people have had it."



Jackson was known for far more than his music though. Speaking after his death in Los Angeles was announced, U.S. civil rights campaigner Rev. Al Sharpton paid tribute to the work of a "trailblazer" in helping people around the world through his charities. How will you remember Michael Jackson?



Sharpton added that the song Jackson co-wrote with Lionel Richie, "We Are the World," a 1985 charity single that raised an estimated $50 million for famine relief in Africa, ushered in Live Aid and the era of celebrity philanthropy.



Jackson was the supreme showman who had an unrivalled knack of grabbing headlines. From his precocious abilities as the 11-year-old singer in the Jackson 5 to his legendary "moon-walk" dance, the star craved attention, and was rarely disappointed.  Jackson "as big as it gets" »



But in the years after his colossal 1982 hit album "Thriller" and its 1987 follow-up "Bad," much of the focus did not cast him in a good light.



In 1996 the lead singer of Pulp, Jarvis Cocker, caused a furor at the Brit Awards in London when he invaded the stage during Jackson's performance of "Earth Song" in protest "at the way Michael Jackson sees himself as some kind of Christ-like figure with the power of healing."



Jackson failed to see the humor in Cocker's mockery, responding that he was "sickened, saddened, shocked, upset, cheated, angry" by the protest. He also alleged that Cocker had attacked children on stage, something that the Pulp singer denied. But many in the music industry backed Cocker, who was arrested but later released without charge.



The theme of children was one that continued to haunt Jackson. In 2002 he caused a public outcry by dangling his baby son Prince Michael II from a third-floor hotel balcony in Germany before the world's press. He later said he regretted the incident.  Watch video of the incident »



And in a 2003 interview with British journalist Martin Bashir that was supposed to repair his image around the world, the singer revived allegations of child abuse when he said of sharing a bed with a young boy: "It's a beautiful thing. It's very right, it's very loving. Because what's wrong with sharing a love?"



A warrant was issued for his arrest on charges of sexually molesting 12-year-old Gavin Arvizo. Jackson surrendered himself to police amid a media furor.



In the 2005 trial conducted in the glare of the world's media spotlight, Jackson was cleared of child molestation charges. Following the trial, Jackson's finances took a hit and he was forced to
