This coming week, 14 to 19 November, is the second Captioning Awareness Week.
Organised by charity Stagetext, the campaign seeks to make the arts accessible for deaf, deafened and hard of hearing audiences.
The week's activities hope to raise awareness and encourage organisations who have not previously used captioning to take up a special offer and support the "name in the frame" initiative through social media.
The UK has an estimated 11 million people with some degree of hearing loss and recent research shown as few as 25,000 people benefited from a captioned or live subtitled event.
Those already supporting Captioning Awareness Week by holding captioned and live subtitled events include Bradford Theatres, Everyman Theatre Cheltenham, New Victoria Theatre Woking, Mayflower Theatre Southampton, Theatre Royal Brighton and Sheffield Theatres with National Theatre, Shakespeare's Globe, Wellcome Collection, New Diorama, Young Vic Theatre, Theatre Royal Drury Lane, The Nest and Queen's Theatre in London.
