BUSINESS INSIDER UK - June 11 - Match Group shouldn't be worried about Facebook's entrance into online dating, Jefferies analyst Brent Thill says. Companies that have experienced a Facebook intrusion have historically seen solid share performance after the social-media company entered their business. Evidence shows users are prone to staying on Match, even if they also choose to use Facebook. Plus, it's not as if using one dating app means cancelling one's account on another. In a survey of 600 users, Thill found that 61% of users said Facebook's service will be an "additive" to the market, rather than a takeover of the market. Additionally, 60% of respondents are on more than one dating app.
