The following is from WWE.com:
This past Friday, SmackDown made MyNetworkTV history for the 12th time, generating the most-watched telecast in the network’s history. The episode, in which John Cena‘s pursuit of Edge‘s World Heavyweight Title earned Big Show‘s wrath, garnered a 2.3 rating, having been watched in 2,660,000 households throughout the U.S. with 3,996,000 total viewers.
This record is coupled with the fact that more men watched SmackDown than any program on ABC, NBC or Fox, and more people watched SmackDown than any show on CW or both NBA games on ESPN combined.
