Primetime Olympics ratings took a dip Wednesday night.

Overall, NBC’s viewership was still huge: 30.8 million viewers tuned in for events such as swimming, diving and gymnastics on the broadcast network last night.

But those numbers represent the lowest Olympics viewership so far this week. Sunday had 36 million viewers. Monday delivered 31.6 million. Tuesday jumped to 38.7 million viewers.

It’s worth noting that the first six nights of Olympics coverage — including last night — have still been higher rated than the first six nights of the previous two Summer Games in Beijing and Athens.
