Four sources for audio and video streams

Here you can have access to the NPR of the NYC region.  It could be useful if you want to improve your listening comprehension of American English.  You can listen to the live FM broadcast or go their show archives.  I personally like Radiolab, Selected Shorts and Fresh Air among the shows they air.
Here you can have access to the BBC website, which also airs on the WNYC in the mornings Brussels time.  It could be useful to improve your listening comprehension of British English.  They also have links under "Learning English", where you can find numerous tools for learners of English as a second language.
Here you can have access to the audio and video streams on The Economist website.  This again is a good source for improving British English listening comprehension.
Here you can have access to TED, which is a good source for numerous talks on a very wide range of topics.  Most talks are given by Americans and Canadians, but there are also other speakers of different nationalities, including some British.
