From that website, which is where the data is comming from, Utah has reported revenues through 06/2013 of 51Million. BYU's reporting period, for reasons unknown, ran to the end of the year, I think, and showed 60Million.
I have no doubt that Utah's revenues will exceed BYU's at some point. But I haven't seen good evidence that it has happened yet.
