Advocacy groups have sued Hulu in an effort to force the subscription streaming service to provide an audio track that helps people who are blind and visually impaired enjoy TV shows and movies.
The federal lawsuit filed in Boston on Monday accuses Hulu of violating the Americans with Disabilities Act for failing to make its services accessible to blind customers.
Audio tracks provide descriptions of a scenes, facial expressions or actions. The lawsuit also seeks to make Hulu's website and applications accessible to people who use screen readers.
The lawsuit was filed by advocacy groups and a blind couple.
