The online dating scene has changed dramatically over the last couple of decades, and more Americans than ever are looking for their perfect match on the web.
Looking for your future partner online is no longer thought of as something reserved for only the socially awkward or desperate.
That study was funded by the dating site e Harmony.
In Britain around 20 per cent of heterosexual couples met online and 70 per cent of homosexual couples.
Findings, published in the journal Proceedings of the National Academy of Sciences, put the percentage of married couples that now meet online at almost 35% -- which gives what may be the first broad look at the overall percentage of new marriages that result from meeting online.
About 45% of couples met on dating sites; the rest met on online social networks, chat rooms, instant messaging or other online forums.
One in five young adults aged 25 to 34 have used online dating versus just 9% of seniors aged 55 and up.
Despite there being such a wide variety of dating sites out there, one still manages to outshine the competition.
“Even though a large percentage of marriages in recent years have resulted from couples meeting online, looking for partners online may potentially suppress the desire for getting married,” said report author Dr Aditi Paul.
“Furthermore the breakup rates for both marital and non-marital romantic relationship were found to be higher for couples who met online that couples who met through offline venues.” The findings contradict a report from the University of Chicago which suggested that online relationships were stronger.
And the trend shows no signs of slowing with sites becoming ever more specialised.
Couples who want to be matched by their music tastes can now logon to Tastebuds, while Jewish singles can try JDate and those who just want their partner in uniform can try Uniform
