This is mostly based off their 2021 employment reports and my anecdotal evidence based on attending Johnson. USC all the way in this case.
Johnson had at most 3% of people go into the entertainment industry. This is obfuscated by their employment report listing media in "other". Given "other" is shared by "Entertainment/Media, government, human resources, non-profit, and retail," we can assume it's lower than 3%. USC dwarfs this with 13% going into media/entertainment.
USC also seems to beat Johnson for Tech PM. Both are kind of cagey exactly what qualifies as "product management" (since CPG and banks have similar roles), but USC boasts 11% and Johnson 6%.
So with the raw numbers out of the way, I would just say you're picking two very uncommon MBA paths. I'm recruiting for Tech PM, and recruiting for Tech PM is extremely unstructured and risky. It's almost completely random, and late occurs later than IB and consulting. I don't know anything about media, other than it being extremely competitive and most roles you do not need an MBA for.
My recommendation for what you're looking for would be NOT to get an MBA, but if you really feel like you need it, USC seems far and away the better choice.
