US online dating sites looking to refresh themselves

New York

NOT many Americans have heard of Spark Networks but far more are familiar with what it owns: JDate, ChristianMingle and a host of other sites like SilverSingles.com and BlackSingles.com.

JDate, especially, would seem to be one of the success stories of online dating. High brand recognition. Stories about happily married couples who met on the site. And last year, with the acquisition of JSwipe, it branched out into the Tinder-like market of users who swipe left or right to find love.
