The BBC is to increase diversity by investing £100 million of its TV budget over a three year period to produce diverse and inclusive content.
Director general Tony Hall has described the move, which will apply from April 2021, as a big leap.
The BBC has set itself a mandatory target - 20% of off-screen talent must come from under-represented groups.
That includes those with a disability or from a disadvantaged socio-economic background.
The announcement follows widespread Black Lives Matter protests, after the death of George Floyd while in police custody in the US.
