How do you transition out of a journalism career?

I have been a business journalist for a b2b publication for the past 8 years, but I have 13 years of journalism experience in total (mostly writing about the restaurant industry, but also technology and pop culture).

For those of you who have managed to make the big transition, how did you do it? Any other types of writing or marketing/PR jobs I find require some kind of related experience that I don't have because I have been in journalism my whole career. The only tangentially related jobs I've applied to are copywriting for companies I've covered in my job and commercial editorial/content producer roles for companies that require writers. Of course, I've never heard back from these.
