USA TODAY - Feb 13 - The mobile dating revenue is projected to double over the next five years ($415M). There is a site for everybody, many with their own apps as well. The niches range from ethnic, religious or age-based to sites for occupations (FarmersOnly.com) or eating preferences (VeggieDate.org). For gay men, there's Grindr.com and Stagg, DateMyPet for pet lovers. With the dating industry moving so rapidly, the phrase "online dating" will soon disappear from the lexicon, says Sam Yagan, CEO of Match. "The idea of differentiating online and offline in five years will be anachronistic," he says. Nielsen reports that the number of Americans using apps or a mobile version of a dating site was 13.7M in November 2012, more than double the previous year's 5.8M. Mark Brooks, a consultant who has studied the industry from its infancy, says the online and mobile dating industry is more than just a business: "Going from where it is now and where it's going to be in the next 20 or 30 years time, I'd be hard-pressed to think of a business -- outside of the medical industry -- that will have more impact on society."
