I've only just come across the excellent TeaTime-Mag, but it's been going for at least a couple of years. As it's published twice a month, there's a big collection of articles in the archive. One thing they don't mention in the video is that there are three versions of the magazine: for speakers of French, German, and Spanish, which is great is you are ... French, German, or Spanish. It's a pity there isn't an all-English version, but even if you don't speak any of those three languages, don't be put off — there's still plenty of interesting material to read and watch in English. There's also a Teacher Edition with extra content including texts with MP3 versions, and vocabulary lists. All in all, an impressive resource — and it's free.
