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 without the help of collaborators, and that he is responsible for the success of his numerous albums. Dr. Dre's prominent studio collaborators, including Scott Storch, Elizondo, Mark Batson and Dawaun Parker, have shared co-writing, instrumental, and more recently co-production credits on the songs where he is credited as the producer. Anderson Paak also praised Dr. Dre in a 2016 interview with "Music Times," telling the publication that it was a dream come true to work with Dre. It is acknowledged that most of Dr. Dre's raps are written for him by others, though he retains ultimate control over his lyrics
