It's episode 500 of Inside PR. Thank you for listening to the first 500. And now,we're starting the next 500. Episode 1,000, here we come! This week we talk about positive steps by Twitter, Facebook and Netflix to promote authoritative news sources and video news magazines. A new news ecosystem takes shape? The Web is almost 30 years old. And the Web's inventor, Sir Tim Berners-Lee, wrote a thought-provoking article about the threats to the Web. Well worth reading and considering. Something about which we all should be taking action.
