In the UK, the Arts Council recently announced its funding plans for the next three years (2015-18) and produced a detailed report on opera and ballet funding. One thing that caught my eye, buried in the report was that companies would be required to include screenings of opera and ballet as part of the "success measures" within their business plans for the period.
The Royal already have an established plan for ballet screenings, but some of the other companies supported do not. Perhaps this might make more productions more widely available.
The report is at
(It's an interesting read. Heartening to see that the audience for ballet in the period examined - 2008/9 to 2011/12 - seemed to grow substantially).
