Undergrad admissions boasts about a 75% acceptance rate, but I haven't been able to find any information about the graduate acceptance rate or the MS in Publishing acceptance rate.
Those 10+ alumni interviews are the best source of information that I've found thus far. There's plenty of information about the University, but few details about the publishing program.
Maybe this will help. In particular, read Kimberly Guinta's interview, where she briefly touches on some of the differences between NYU and Pace.
