Fans of dark TV comedy Nighty Night will be able to preview clips of the second series on video mobile phones.
Julia Davis writes and stars in Nighty Night
The BBC Three show, written and starring Julia Davis, has won a British Comedy Award and a Royal Television Society award for best sitcom.
The clips will also be available from the channel's website ahead of the sitcom's broadcast on 6 September.
The pilot follows the experiment where the first episode of The Mighty Boosh was premiered online.
Each episode of the surreal Mighty Boosh is being streamed via broadband ahead of transmission on BBC Three.
The experiments are part of the BBC's look at how TV programmes can be delivered outside of the traditional broadcast using new technology.
Nighty Night also stars Angus Deayton, Marc Wootton and Mark Gatiss.
In the show, Davis plays a beautician who tries to seduce her next door neighbour, whose wife is wheelchair-bound.
