According to a new study published by the National Bureau of Economic Research, couples who have a TV in their bedroom, on average, have 6 per cent less sex than those who do not.
The research included 4 million people across 80 countries and 5 continents.
"Our findings are consistent with people demonstrating some willingness to substitute electronic companionship for human companionship,” says Nicholas Wilson, associate professor of economics at Reed College in Portland, Ore.
“More recently, popular culture has claimed that smartphones are killing peoples sex lives,” write the authors.
“Our study population resides in low- and middle-income countries and were surveyed largely around 2010, before the widespread availability of smartphones. In countries with ubiquitous smartphones, the smartphone might be the real sex-life killer.”
The results also found that income, age, and education didn't impact the sexual activity of TV owners.
