The impact of video relay services, or VRS, has been titanic for businesses owned and operated by the deaf. VRS has grown into a half-billion-dollar-a-year industry as more and more deaf Americans gain access to speedy mobile data and sophisticated phones. It’s changed forever not only the way that Mozzeria, a pizzeria in San Francisco, California, and other deaf-run restaurants do business, but how the deaf navigate a world made for the hearing. In fact, VRS ranks among the biggest-ever leaps in deaf communication with the hearing. And it’s all free, thanks to you.
