While the influx of the dot.com world eliminated the need for brick-and-mortar locations for all stores (think eBay or Amazon), all of the above categories typically had a headquarters, if not multiple locations where one could visit and interact.  This would ensure a unique experience, often depending on the individual needs of the visitor. For instance, when visiting a municipal building or institute of learning, a variety of methods are available to get to higher floors (stairs, elevators, ramps and escalators).
Any business that is considered a “place of public accommodation” is required to provide equal access to services under the nondiscrimination requirements of Title III of ADA. When you look at the guidelines closely, this includes hotels, entertainment venues, legal and accounting firms, retail stores, and virtually every business that is not a private club, including businesses that exist solely on the web.
According to the DOJ, “Being unable to access websites puts individuals with disabilities at a great disadvantage in today’s society.” With these words in mind, the DOJ has rapidly adopted the role of web accessibility enforcer. A failure to make digital content, including websites, accessible to all individuals regardless of their emotional, physical, or mental disabilities, can result in hefty fines and class action lawsuits. In short, the DOJ is dedicated to making sure that individuals with disabilities have the same equal access to the benefits that are available online. Creating equal access is only possible if organizations a) understand the requirements of web accessibility, b) know that web accessibility is an obligation under the ADA, and c) make web accessibility a priority. The value that awaits when organizations adhere to digital accessibility laws can be measured in more than dollars and cents.

Courts have essentially taken three positions when approached with this issue. Some courts take the position that the ADA applies to all commercial sites because the law was meant to protect disabled individuals from having a more difficult time than able-bodied individuals from doing business. That is why the website Scribd was unable to get a case summarily dismissed and ended up settling.
The ADA is the Americans with Disabilities Act, passed almost 30 years ago in 1990. This act was originally put in motion pertaining solely to physical location. It requires establishments to provide people with disabilities easy access to various levels throughout the business. This act was set to achieve an equal experience to all people, handicapped or not.
