Couples who meet online are more satisfied in their relationships and are less likely to break up than those who get together in bars, the workplace or on blind dates.
Researchers in America found more than a third (35pc) of couples who married between 2005 and 2012 met on the internet, with 45pc of those using dating websites and 21pc finding each other on social networks.
The academics from the University of Chicago, Harvard University and Gestalt Research said their work shows "evidence for a dramatic shift since the advent of the internet in how people are meeting their spouse".
They questioned 19,131 respondents from across the US and found the percentage of marital break-ups was lower for those who met their partners online (6pc) than in more traditional places (8pc).
Couples who got together over the web also reported greater marital satisfaction, the researchers said.
Most couples who met in offline environments found each other at work (22pc), or through a friend (19pc), while 11pc met at school and 10pc at social gatherings.
Of currently married couples, those who met through school, place of worship or social gathering reported the highest levels of satisfaction.
