According to the 'Shaping the Future Implications of Digital Media for Society' report of the World Economic Forum, 21 per cent of those surveyed said they spend more than three hours per day chatting and messaging.
The findings are based on a survey of over 5,000 digital media users from Brazil, China, Germany, South Africa and the US.
The report said one out of six users believe it has a positive effect on maintaining relationships with friends, while two-third believe it helps them do their work, like building relationships with professional contacts, collaborate with colleagues, learn and develop professionally.
Millenials spend on an average more than seven hours a day online, on their smartphones or on multiple devices such as laptop and personal computer, at the same time. Millenials are those born after 1980.
