Ultimate Fighting Championship
The Ultimate Fighting Championship is the largest Mixed Martial Arts organization on the planet after recently buying out their top competitor, PRIDE. Originally begun in the mid 1990s as a way to showcase martial artists of different disciplines facing each other, the sport has evolved into weight classes and extra rules so that it could be accepted by the mainstream. The fighters have evolved as well. It is rare to have a fighter practice only one discipline. The fighters that win are usually well rounded in all facets of fighting. The current president of the UFC is Dana White.
On July 9, 2016, the UFC announced that it would be sold to a group led by WME-IMG, its owner Silver Lake Partners, Kohlberg Kravis Roberts, and MSD Capital, for $4 billion. Flash Entertainment (owned by the government of Abu Dhabi) will retain its 10% minority stake in the company, and White will also retain a stake.
Performance enhancing drugs
The UFC is subject to the world-wide regulation of athletes to regulate the use of performance-enhancing drugs. UFC athletes are tested for illegal drug use by the United States Anti-Doping Agency (USADA) which in turn is regulated by the World Anti-Doping Agency (WADA). The UFC Anti-Doping Program began July 1, 2015. Prior to WADA regulation, there was a widespread use of drugs by UFC athletes. The first three months of the program focused upon educating UFC athletes about what drugs are prohibited by WADA. Since then, a number of prominent UFC athletes have tested positive for illegal drug use, including: Brock Lesnar, Mirko “Cro Cop” Filipovic (suspended for two years), Janigleison Herculano Alves aka Gleison Tibau (suspended for two years),  and Diego Brandao (suspended for nine months).
Some of the drug suspensions did not arise from attempts to enhance performance. For example, Chad Mendes was suspended for two years when a cream he used to treat plaque psoriasis contained an ingredient that was a banned substance.
