Director general Lord Hall has announced his vision for the future of the BBC, including a "stronger" World Service and working in partnership with other news organisations.
Here are some key questions and answers about the proposals:
::Why are the changes being made?
Lord Hall's speech was the first of a four-part response to the Government's review of the BBC's royal charter, which runs out at the end of next year.
The renewal of the charter is an opportunity for Parliament and the public to influence how the BBC is financed and operated.
Culture Secretary John Whittingdale previously questioned if the corporation should be "all things to all people" and Chancellor George Osborne criticised the website for "becoming a bit more imperial in its ambitions".
:: How much money does the BBC have to save?
The BBC will be forced to make savings of around 20% by 2020, as well as facing an increasing decline in revenue from licence fees as more and more people watch programmes online.
It has agreed to cover the cost of free television licences for people aged over 75, which is estimated will cost the organisation around £750 million, a fifth of its annual income.
Lord Hall has indicated he will not announce where the cuts will be made before December.
:: What services will be affected by the changes?
It is likely there will be a cut to services to meet the savings imposed by the Government.
But it is unclear what channels or programmes will be affected and the answers are not expected until the final response, due to take place in December.
A number of new services have been announced, including iPlay, an on demand service for children, and the Ideas Service, a partnership with arts and science organisations.
:: What effect will the proposals have on other news organisations?
The BBC has pledged to make its content to other news outlets, including local newspapers and radio stations.
It will also provide a "platform" where partner organisations will be able to share their content.
In a promise to help support local democracy the broadcaster will create a "network of 100 public service reporters across the country" which will be available for "reputable" news organisations to cover councils, courts and public services in the UK.
