In addition, covered entities are not required to provide any particular aid or service in those rare circumstances where it would fundamentally alter the nature of the goods or services they provide to the public. In the performing arts, for example, slowing down the action on stage in order to describe the action for patrons who are blind or have vision loss may fundamentally alter the nature of a play or dance performance.

Through the Americans with Disabilities Act (ADA), our nation committed itself to eliminating discrimination against people with disabilities. The U.S. Department of Justice’s (DOJ) Civil Rights Division is proud to play a critical role in enforcing the ADA, working towards a future in which all the doors are open to equality of opportunity, full participation, independent living, integration and economic self-sufficiency for persons with disabilities. 

The DOJ is currently working to release new technical standards for digital accessibility. The latter updates to the ADA guidelines will be in conjunction with the latest version of WCAG 2.1, which includes the most widely accepted digital accessibility requirements across the globe. If organizations want to overcome the current limitations of ADA guidelines, then they should follow the WCAG 2.1 checklist,11 as well as the suggestions provided by the ADA. The latter two steps, combined with the help of a trusted digital accessibility compliance platform,12 can help organizations achieve digital accessibility best in class standards throughout all of their digital formats and across all media.
For discussion’s sake – while I don’t know the specific nature of your videos, my guess is that they might be demonstrating various techniques or other content in which simply hearing the audio of the video wouldn’t deliver the full context of the content. If making that content accessible is something you’d want to do, you’d likely want to start with a written description of what takes place in the video. Beyond that, high contrast vector images or diagrams showcasing specific parts of the technique would certainly help.

As a web developer, Ryan's work is what makes the magic happen. He spends most of his time creating custom websites, which involves turning the designers' visual mockups into code. It's lucky that he's such a good problem solver, because many of Ryan's projects involve working with clients to create complex custom functions. He's also one of the few developers in the country with extensive experience developing for the HubSpot CMS.

In recent cases, the U.S. Department of Justice has repeatedly sided with plaintiffs arguing that a private company’s website needs to be accessible, despite any other mitigating factors. One thing is for certain, however: The number of federal lawsuits alleging violations of the ADA is currently accelerating at a rapid pace. Between January and August 2017, there were 432 ADA lawsuits filed in federal court—more than the total number of ADA lawsuits in 2015 and 2016 combined.
Regarding examples of accessible websites, I would suggest the Accessiweb gallery: Accessiweb is a reference list 100% based on WCAG2, and they deliver quality marks (the "Accessiweb label") upon website owners solicitation. The website undergoes a thorough manual review (on a carefully defined 10-page sample, more or less), and it gets the label only if it's flawless on every page. The level is reflective of the number of defects found and not corrected. Bronze is exactly equivalent to level A, Silver to AA, and Gold to AAA. So getting a Silver label means all A and AA tests were passed on all of the sample. Bronze, two stars: All A tests were passed, plus 50 to 75% AA tests. And so on.
In short, the ADA is meant to protect disabled individuals as they go about their daily lives. These regulations ensure that people with disabilities are not denied entry into the above places or denied services by a company due to their disability. It is important to note that these regulations are now applicable to services that are provided online or through other digital formats. For example, if a company accepts job applications online, then it must ensure that a person with a disability can also apply for the job online. In other words, it is illegal to have barriers on the website that would keep the disabled individual from successfully completing their application. Fortunately, the ADA guidelines help to remove barriers and ensure that the Internet remains a space that people of all backgrounds and disabilities can use.
The landscape of disabled access litigation related to online services has significantly changed and expanded over the past decade. Initially, the internet was an area of little concern as courts uniformly held that the ADA applied to "brick and mortar" facilities, not to cyberspace. This has changed and online accessibility is presently, and will continue to be, an area of significant investigation and litigation.
You probably won't have to check your site with all of the available evaluation tools out there, but it is a good idea to do so for the most common web browsers. Just as accessibility software makes it easier for people with disabilities to navigate the Internet, these tools make it easier for developers to ensure accessibility from the start. When you think you've mastered it, go back through the Section 508 compliance checklist to ensure you've met every goal.
