The number of television viewers through the first four nights for the London Games puts it on pace to be the most watched Olympics ever, despite heavy criticism of NBC's tape-delayed primetime coverage. The network is averaging an 18.9 final rating and 34.8 million viewers, up 10 percent and 14 percent, respectively, from the Beijing Olympics four years ago, according to the Sports Business Daily. The rating is the highest since the Atlanta Games in 1996 and the average number of viewers is on a record-setting pace. Monday night's coverage earned NBC an 18.0 final rating, up from the 17.6 for the same night in Beijing and 16.6 in Athens in 2004. The overnight Tuesday rating was a 24.0, according to the Daily, which would be the highest-rated night of the London Games if the number stands.
