> I would expect a CPM around 1 cent. Still, times 50 million, it isn't nothing.

CPM is cost per mille, AKA cost per thousand impressions. Revenue from 50,000,000 impressions would be CPM * 50,000.

Thanks for specifying this. There's a typo/arithmetic error in the original comment, which led me to assume CPM must mean 'per 100'.
