About 1.6 million people registered online for a lottery to win tickets for the 11,000 seats inside the sports arena and 6,500 seats to watch the service on large video screens at the nearby Nokia Theatre.
Craigslist and eBay have been busy pulling ads for memorial tickets off their site, some going to tens of thousands of dollars. The family was adamant that the tickets not be scalped and the Los Angeles Police Department is prepared to charge those they catch.
Other ads that have popped up in the last two days were not for actual tickets, but just for a copy of the e-mail sent by the Staples Center confirming entry for the tickets.
While some were aiming to take advantage of the opportunity to attend the service, others were offering their tickets online for free, wanting them to go to true Jackson fans that would appreciate them.
Fans have flocked from all over the world to attend today's memorial, pulling into the area which is heavily cordoned off by police. One man said learning he had gotten tickets was like being accepted to college.
Another woman pulled in yelling "God Bless Michael!"
Azzi Kashani from O Hotel said, "It is exciting and sad at the same time ... it's probably going to be one of the largest funerals, memorial services since Princess Diana."
All the fans, celebrities and police patrols may have made the scene outside the Staples Center seem like a circus, but there were also 11 elephants and seven horses on hand. Ringling Brothers and Barnum & Bailey circus is scheduled to open Wednesday at the arena and in preparation, it was scheduled to bring the animals into the side entrance of the complex before dawn.
Not present was Debbie Rowe, Jackson's second ex-wife and the mother of his two eldest children. A spokesman told "Good Morning America" Monday that she would be there in VIP seats, but her lawyer announced just hours later that she would instead stay home and mourn privately to keep the attention on Jackson and his legacy.
Frank Cascio, close friend of Michael Jackson, told "GMA," "I think he would be humbled by the world right now. He would be very humbled."
Roger Friedman of The Hollywood Reporter says that a huge memorial concert is being planned for Michael Jackson's 51st birthday on Aug. 29 at London's O2 Arena.
