FORTUNE - July 19 - Mandy Ginsberg has had an interesting first year as CEO of Match Group. She recalled the moment she learned that Facebook had entered the dating arena. She had just finished preparing remarks for an earnings call, when her phone began blowing up with the news. "The stock started dropping a dollar a minute," she recalled. "I just threw all my prepared remarks away and started over." Ginsberg feels confident that the mostly young love-seekers don't want to be dating on the same platform where their parents hang out.
