The American with Disabilities Act (ADA) was started in 1990. The ADA makes it illegal for any government or business entity to provide products or services that are not accessible to people with disabilities. If the technology already exists where the general public can order a product, apply to a job, et al at any time of the day or night, then this ability must be available to people regardless of their abilities.
Title III of the ADA focuses on web accessibility. It states that any business or organization that serves the public (also known as “public accommodations”) must be accessible regardless of digital format. The Department of Justice confirmed that Americans with Disabilities Act applies to public accommodation websites, also.
