THE GUARDIAN - "We [gay men] kind of created the concept of online dating," claims Grindr's CEO, George Arison. Prior to Grindr, gay men had found connection through a variety of means, including classified ads, phone chat lines and, during the late 1990s and 2000s, dating sites such as Gaydar and Manhunt, with the former having 5M subscribers in 2009. While Match.com was launched in 1995, before Gaydar and Manhunt, Arison claims many straight people were still "weirded out" by the concept of online dating at that time. Then, in 2009, along came Grindr. Founded and launched by Joel Simkhai just nine months after Apple added GPS functionality to the iPhone, it was one of, if not the first popular location-based dating apps in the world, a full three years before Tinder was launched. Fifteen years on, its core functionality remains largely unchanged. It allows users to chat with other gay and bisexual men in their immediate area (with location details down to the number of feet away another user is) and arrange to meet up - often for sex.
