The BBC has unveiled a raft of shows across radio, TV and online that it hopes will win over a teenage audience.
Annie Mac will present a TV and radio show for BBC Switch
The multimedia project, called BBC Switch, will include a weekly new music show, a coming-of-age TV soap and an interactive online drama.
BBC Switch head Geoffrey Goodwin said delivering content to audiences aged 12 to 16 was of the "utmost importance".
It is part of the corporation's drive to keep young viewers and listeners in an age of unparallelled choice.
Its highlights include a fast-paced music show called Sound, presented by Radio 1 DJ Annie Mac, shown on BBC Two on Saturday afternoons.
Sound will be filmed at outside locations across the UK instead of in a studio.
Switch's online arm will broadcast Signs of Life, an eight-episode show centring on astrological events in an English village that lets viewers interact with the plot.
The website will also contain useful information for the age group, such as advice for personal issues and relationships.
Other Switch content will include:
- The first Radio 1 under-18s concert at Wembley Arena in November, featuring UK and international artists.
- A drama called Falcon Beach, based on a group of Canadian teenagers, which will be aired on BBC Two.
- Radio 1's Sunday night advice show The Surgery, which will be hosted by Kelly Osbourne.
- A new show on Radio 1, called Switch, will feature specialist music and live tracks, to be hosted by Annie Mac.
- A definitive web guide to the "tribes" that exist in the UK today.
- Slink, an online magazine for girls aged 12-16 offering entertainment, chat and advice.
