Commissioner Bud Selig said after Game 1 that he was happy with that particular rating.
"I think we're doing remarkably well," Selig said.
Overall, the rating for the World Series is an 8.0 with a 14 share, down 25 percent from last year's Red Sox victory over the Rockies, which ended in four games. A single ratings point for over-the-air TV in the U.S. is about 1.1 million viewers.
The share is the percentage of households tuned in to a particular show or event.
This year's numbers are a bit skewed, because Saturday night's rain-delayed Game 3 drew a 6.1 rating. The game began at 10:06 p.m. ET and didn't end until 1:47 a.m., with the Phillies winning, 5-4, in the bottom of the ninth, although the 6 rating held for the final few hours of the game.
"It was a terribly difficult situation," Selig was quoted as saying in the Sports Business Daily about his decision to hold that game until rain stopped 91 minutes after the scheduled start time. "You know what? It was a great game, and those who saw it enjoyed it."
