World Extreme Cagefighting owned by Zuffa LLC
World Extreme Cagefighting (WEC) was an American mixed martial arts (MMA) promotion founded in 2001. It was purchased by Zuffa, LLC, the parent company of the Ultimate Fighting Championship (UFC), in 2006.  In its final incarnation, it was made up of 3 weight classes: 135 lb (61 kg), 145 lb (66 kg) and 155 lb (70 kg). To accommodate the smaller fighters, WEC's cage was 25 feet (7.6 m) in diameter—5 feet (1.5 m) smaller than the standard UFC cage.  The smaller cage is now used by UFC for selected events.Media coverage
On December 11, 2006, UFC parent-company, Zuffa, formalized plans to buy World Extreme Cagefighting, to be run as a separate promotion from the UFC. Following the purchase of WEC, Zuffa made several changes to the promotion. One of the most noteworthy changes included added media exposure when WEC signed a deal to air events on Versus beginning with WEC 28. Prior to this WEC had broadcast most of their events on HDNet.
While on Versus, most events aired mid-week, or on Sunday nights during the summer months. WEC drew good ratings that averaged around 575,000 average viewers per event. However ratings ranged from 245,000 to 1,500,000.
The biggest ratings draw for WEC was Urijah Faber. When Faber was featured in the main event he drew an average of 840,000 viewers. Faber was also featured in both main events (34 and 41) that drew over a million viewers for WEC.
