Following the launch of "Daredevil" in April 2015, Netflix director of content operations Tracy Wright announced that Netflix had added support for audio description (a narration track that contains aural descriptions of key visual elements for the blind or visually impaired), and had begun to work with its partners to add descriptions to its other original series over time. The following year, as part of a settlement with the American Council of the Blind, Netflix agreed to provide descriptions for its original series within 30 days of their premiere, and add screen reader support and the ability to browse content by availability of descriptions.
