The BBC is known for producing radio plays, but the format is about to get a high-tech twist: a new experiment by the broadcasting company will turn traditional audio dramas into interactive stories.

One new radio play — a comedy / science fiction story titled The Inspection Chamber — will work similarly to a choose your own adventure book or game. Listeners will hear a chunk of the story, and then be presented with a choice of what should happen next. It was developed by the BBC’s R&D division, which worked with an audio company called Rosina Sound. The piece is said to take inspiration from games like The Stanley Parable and Papa Sangre, especially in terms of exploring new ways to offer interactive fiction. You can listen to some of it now over at the BBC’s R&D blog.
