This is a bit different. There are some accomplished programmers, software architects, etc. who don't have CS degrees, I think it's fair to say that they are in the distinct minority. On the other hand, I suspect that, among the top tier of journalists (admittedly difficult to measure), the majority--perhaps the great majority--do not have J-School degrees. There are better (e.g. Columbia) and worse journalism schools, for sure. But it's not the sort of prerequisite that other professional degrees can be.
