Video Killed the Radio Star by The Buggles
'I heard you on the wireless back in 52
Lying awake intent at tuning in on you.
If I was young it didn't stop you coming through.
Oh-a oh.
They took the credit for your second symphony.
Rewritten by machine on new technology,
and now I understand the supernova scene.
Oh-a oh. I met your children
Oh-a oh. What did you tell them?
Video killed the radio star.
Video killed the radio star ...'

E. Writing for radio news is a visual experience
When writing news stories for the radio, reporters try to use simple, everyday language which paints a picture of the events of the story in the listener's mind.
Task
Write a 30-second radio news story. Remember the 5W's + How: who, when, where, why, what and how.
Write it, voice it, time it, edit if necessary, and now record it, play it and rate it.
Your news writing must stimulate the listener's mind.
