What gave you that idea ?

It was back in September 2015 that the BBC launched its Charter renewal 'big ideas' under the banner "British, Bold, Creative".

Bold they may have been, but the gestatory period seems rather extended. The latest Executive meeting reviewed The Ideas Service, including "a plan for the next stage of development." and 

the findings of the Arts Group, on "what a more 'open' BBC meant for arts and culture in the UK, as well as for the BBC itself - and how it might be delivered."

The Arts Group were asked to return with "proposals for how the project would work in operational terms". Might that take another 13 months ?
