Nesta, the Arts Council England, and the Arts and Humanities Research Council have released Digital Culture 2015.
Here's an excerpt from the announcement:
The 2015 report provides analysis on the period 2013-2015, giving a detailed sense of how the picture is changing for arts and cultural organisations. This year's report shows that while the positive impact of technology on organisations remains high, there is a gap between the ambition of arts and cultural organisations in relation to digital technology and their ability to execute on those ambitions.
