ITV1 sketch show, 'Shoot The Writers' is to return in the Autumn, and they are reading sketches until the end of April. The format has changed, with each episode now including only the work of 6 writers, showing four sketches from each, so it's going to be much more difficult to get your work on TV this time, but surely it's worth a go.

It seems to me that if you are successful this time you will have far greater exposure than the original series, where each episode could have 20+ sketches, all by different writers.
