JournalismJobs.com is a good general media job board. It’s a good place to check, in particular, for print jobs and radio jobs. This website also has more listings throughout the country and does not focus as much on bigger media cities -- L.A., NYC, Chicago, etc. -- as some other sites.
Best Ways to Search
Since this website has listings all over the country, it’s good to break down your search by geographic region. If you’re not particular about where you want to work, then check jobs by the description. There’s a pull down option which allows you to break down your search.
When to Look
Most good job boards update their listings daily. JournalismJobs.com is no exception. That said, there aren’t always a ton of new jobs opening up on a daily basis. If you don’t check daily, this site is definitely worth checking out on a weekly basis.
