Here are a couple of RSS feeds:
- For comedy shows on Radio 4
- Because not all the comedy shows are on the comedy shows page, for all shows on Radio 4
I've only been trying these out for a couple of days, so I'm not sure how well the feeds are going to handle shows coming and going off the listings page, but they should pick up the start of new series, which was the main idea.
Unfortunately, there's no way to indicate when a new show of a weekly series is broadcast - the BBC will have to produce feeds for that.
For starters, I recommend Museum of Everything and That Mitchell and Webb Sound.
