Dr. Dre in Santa Monica, California. An exclusive laptop, known as the HP ENVY 15 Beats limited edition, was released for sale October 22. In May 2014, technology giant Apple purchased the Beats brand for $3 billion, Apple's most expensive purchase by far. The deal made Dr. Dre the "richest man in hip hop", surpassing Diddy. During May 2013, Dr. Dre and Jimmy Iovine donated a $70 million endowment to the University of Southern California to create the USC Jimmy Iovine and Andre Young Academy for Arts, Technology and the Business of Innovation. The goal of the Academy has been stated as
Dr. Dre Achievement Award. Knight immediately went on CBS's "The Late Late Show" to deny involvement and insisted that he supported Dr. Dre and wanted Johnson charged. In September 2005, Johnson was sentenced to a year in prison and ordered to stay away from Dr. Dre until 2008. Dr. Dre also produced "How We Do", a 2005 hit single from rapper The Game from his album "The Documentary", as well as tracks on 50 Cent's successful second album "The Massacre". For an issue of "Rolling Stone" magazine in April 2005, Dr. Dre was ranked 54th out of 100 artists for "Rolling Stone"
