NHK, the Japanese public broadcaster and the largest broadcaster in Asia, will use Twitter for a live TV special called "SAVE THE FUTURE". Twitter will be used to connect the studio and the viewing public.
Just another example of taking your conversations to where the people are already at as opposed to expecting them to come to you. As we all know, people are coming together around conversation and community. NHK has obviously figured that out.
Their presence on YouTube is also impressive.
