BBC Cymru Wales is to launch a second Welsh language radio station.
Radio Cymru 2 will broadcast from 07:00 to 10:00 each morning on digital radio, digital TV and BBC iPlayer.
The new station will offer a mix of music and entertainment, while the existing Radio Cymru station will maintain its morning news service.
It follows the trial broadcast of a second Welsh language station, Radio Cymru Mwy, last year to celebrate its 40th anniversary.
Betsan Powys, Radio Cymru editor, said: "This is a truly historic announcement - one of the most important since Radio Cymru was established in 1977. Our listeners are some of the most loyal in Wales and the fact that we can now offer a choice of listening is incredibly exciting."
Radio Wales editor Colin Paterson said: "These are unprecedented times of change for Wales, and I'm delighted that this major expansion for Radio Wales on FM will ensure listeners in every part of Wales can enjoy access to our wide-ranging news, sport and entertainment programming, as well as our superb team of presenters."
