Plans for the future of BBC Three have been announced, including a move to online broadcasting 24 hours a day and an emphasis on long form content.
The remodelled service will offer tailored content based around comedy and thought-provoking programming.
The removal of the channel from digital terrestrial will make room for a BBC One+1 service, while CBBC will be extended by two hours in the evening.
Director general Tony Hall called it an "exciting and ambitious proposal".
He added the proposals - which will generate savings of ÂĢ50m for the corporation - were "difficult decisions" in the face of a frozen licence fee.
The plans will have to be approved by the BBC Trust, who will consult with the public from the beginning of next year.
The future of BBC Three
- The channel will move from nine hours a day to a 24-hour service
- Programmes like Snog, Marry, Avoid and Don't Tell The Bride are likely to be jettisoned in favour of harder-hitting content
- 80% of budget will be spent on long-form programmes like Murdered by My Boyfriend and Bad Education
- 20% of budget will go on non-traditional content - such as micro-videos, listicles and gifs
- A daily news service will be created in conjunction with Radio 1's Newsbeat
- Programmes will not just live on iPlayer, but will be distributed on third party sites including YouTube and Facebook
- Traditional genres like drama and comedy will be replaced by the strands "Make Me Think" and "Make Me Laugh"
- Moving BBC Three to online will allow CBBC to broadcast for an extra two hours in the evening
- It will also allow for a BBC One+1 channel to be launched
The new online version of BBC Three will involve different forms and programming formats, varying durations and interactive content.
Damian Kavanagh, who is leading the proposals, said BBC Three would be "reinvented for the digital age" and reflect the growing trend of young people consuming television online.
"This is not moving a TV channel and putting it online. This is new. We are the first broadcaster in the world to propose something like this," he added.
The new BBC One+1 channel - which will occupy the space left by BBC Three - will enable viewers without access to broadband and iPlayer greater availability to programmes.
The BBC has been keen to stress linear TV is still important for younger audiences.
The corporation's boss Lord Hall added that this was an example of the BBC embracing a new age in broadcasting.
"By searching out new ways to engage and entertain young audiences on their terms, the new BBC Three will be a great example of how we can reinvent the public service for the digital world - using their talent, appearing on the platforms and devices that they use and talking to them as equals and partners," he said.
The BBC's director of television Danny Cohen admitted that the changes would lead to an "initial drop overall" in viewing figures, adding "that's why we want BBC One and BBC Two to pick up the weight".
Mr Cohen said that the introduction of a BBC One catch-up channel was a significant part of the proposals, "because we know those +1 channels are very important to people".
