Last week, singing sensation Pharrell Williams got some unhappy news. His clothing companies, Billionaire Boys Club and Ice Cream Retail Operations LLC, are being sued because their websites allegedly violate the Americans with Disabilities Act. The plaintiff is a visually impaired man who says Williams’ websites didn’t work with screen reading technology, making them inaccessible for him.

The case against Williams’ sites is hardly the first of its kind. Last year, it’s been reported more than 800 cases were filed alleging companies’ websites violated ADA Title III, which “prohibits discrimination on the basis of disability in the activities of places of public accommodations.”
