Voice of America Learning English is a news and information service used by English learners and teachers worldwide. Reports are written in VOA Special English, which is read one-third slower than regular English.
VOA Special English has its own YouTube channel, where you can find over 500 videos. This recent report about using the internet and social media to find a job gives a good idea of what to expect.
