More public sector invasion of YouTube: this time, it’s the NHS. There’s already quite a lot of video in the new NHS Choices site, delivered via Flash from their own local site – see this example on their Asthma information pages. But it’s a very smart move to go into YouTube too… not least in keeping with the principle of going where the audience already is. Not much to see yet, but I’m not even sure it’s been formally ‘launched’.
