I have written odd radio scripts and found it a fascinating exercise to try given you have to use dialogue and sound effects to create your fictional world. And it is a question of getting the balance right too. Too much dialogue kills the story. The sound effects must add to the story and move it on, also without dominating the plot. I hope to write more radio scripts in the future. My bias is towards radio as it is my favourite medium. I do agree with the old saying that the "pictures are better on radio".
In the UK, we are lucky to have BBC Radio 4 and Radio 4 Extra which are talk based stations and cover a wide range of programmes from documentary to drama, from sitcoms to one-off humorous plays. A listen to their schedules shows just what a wide variety of writing is out there and I find that inspiring. As I type this, I am listening to the marvellous The Goon Show, which despite being well over 50 years old, is still as fresh and inventive as when it first went out. Spike Milligan was well ahead of his time in many ways.
I've also found it interesting and inspiring to try and write in different formats, though nothing will take from my joint first loves of short stories and novels. But I think a break from what you usually write can be good for a writer and you may find a love for a format you never knew you had. That happened to me when I decided to "have a go" at writing short stories!
Still, whatever the form of writing you try, you still need a good plot, well rounded characters, that special "spark" which keeps readers/listeners/viewers gripped to what you have written and a very good editor. I take some comfort from the fact Shakespeare rewrote his plays and if rewriting was necessary for him and Dickens, then it definitely is necessary for the rest of us!
No matter what you write, editing is crucial.
