According to WrestleNomics.com, the highest quarter hour of last night's Raw was CM Punk's segment with Seth Rollins. They did 1,881,000 viewers. The preceding segment did 1,504,000 viewers while the segment that followed did 1,432,000. It's pretty clear what moved the needle last night.
In fact, the final two quarter hours were under 1.3M viewers, which is understandable as both NFL games had strong fourth quarters.
