The Online Dating Industry has been adding more and more bells&whistles to marketing strategy since 1995. The 2009 showed big sites like Match, Chemistry, True, eHarmony, PerfectMatch and others have less traffic than 1 year ago or decaying in traffic.

Papers researching on Theories of Romantic Relationships Development with Commitment are the ones the Online Dating Industry needs to achieve innovation!
