Bisping was a huge underdog going into the fight, but showed surprising resilience, stuffing many of Sonnen's takedowns and frequently managing to pin Sonnen against the cage.
However, as is the usual, Sonnen was able to control a significant portion of the fight with his grappling and that was enough to earn him the decision.
Despite the loss, Bisping should be happy with his performance. Many people totally counted him out against Sonnen, but he managed to make it a very close fight.
What we'll remember about this fight
The post fight interview, for starters.
Keeping in line with his usual antics, Sonnen took the microphone from Rogan after the fight and conducted an impromptu interview with the UFC commentator.
Sonnen closed out the interview with a familiar tagline: "When you're the greatest fighter in the world, they don't call you a great fighter, they call you Chael P. Sonnen."
We will also remember the surprising effort turned in by Bisping, who came close to edging the No. 2 middleweight in the world.
After tonight, I think Bisping will start to get the respect he deserves.

What we learned about Michael Bisping
He is an underrated grappler.
Bisping gets little credit as a grappler, but he managed to stuff many of Sonnen's takedowns, scramble back to his feet on multiple occasions, and he even took Sonnen down at the end of the fight.
Few people in the UFC have managed to put up such a fight against Sonnen.

What's next for Michael Bisping
Bisping could very well face the man he replaced this evening, Mark Munoz. Chris Weidman and Rousimar Palhares are also possible opponents.
