Number Crunching: This Week's TV Ratings

• All Olympics, all the time. That's pretty much the story for this week, as the 2008 Olympics dominated the ratings every night — and that's even with some of the major events airing after 11 p.m., when primetime ratings typically cut off. The "weakest" night was Wednesday, when the network averaged 27.2 million viewers.
• Dogging it. Maybe it's just the Olympics talking, but Greatest American Dog has been struggling of late. This Wednesday's episode brought in 5.2 million viewers; its highest-rated episode earlier this Summer drew 9.5 million people.
• Late-night lift. The Olympics are helping at least one other segment of programming: NBC's late-night shows. For example, the episodes of The Tonight Show with Jay Leno and Late Night with Conan O'Brien that aired after the Olympics' opening ceremonies were the highest-rated those shows had been in months.
• Still flashing. One of the impressive notes for CBS this week: Flashpoint held up well even with the Olympics on, drawing 6.3 million viewers on Thursday.
