The programme began its pilot season in June 2009 with a production of Phèdre, starring Helen Mirren, which screened live in 70 cinemas across the UK.
Two hundred more venues eventually showed the production internationally, resulting in a combined audience of around 50,000 people for this one performance.
Most productions broadcast are plays performed in repertory at the Royal National Theatre, but works by other companies have been included.
The Donmar Warehouse's production of King Lear, starring Derek Jacobi was broadcast live from Covent Garden on 3 February 2011.
A Streetcar Named Desire starring Gillian Anderson was broadcast live from the Young Vic on 16 September 2014.
