WASHINGTON - Smartphones are giving a big boost to posting of photos and videos, according to a study released Monday.
The Pew Research Center survey found 54 per cent of US Internet users now post original pictures or videos online, up from 46 per cent last year.
And 47 per cent repost images or videos they discover online, the survey found.
Much of this growth came from people using smartphone apps like Instagram or Snapchat, according to Pew researchers.
This survey found that 92 per cent of Americans own a cell phone and 58 per cent own a smartphone. Some 18 per cent of cell phone owners use Instagram and nine per cent use Snapchat to share images or videos.
"Sharing photos and videos online adds texture, play, and drama to people's interactions in their social networks," said Pew Internet's Maeve Duggan, author of the report.
"This all adds up to a new kind of collective digital scrapbook with fresh forms of storytelling and social bonding."
Women are more active sharers than men, according to the survey: Some 59 per cent of online women post photos and videos they have taken themselves, compared with 50 per cent of men.
Likewise, 53 per cent of women share some of the content they found elsewhere, compared with 42 per cent of men.
Among those in the 18-29 age group, 81 per cent have uploaded original content and 68 per cent have reposted photos or videos.
Some 26 per cent of cell owners in this age group use Snapchat, while 43 per cent use Instagram.
"A lot of photo- and video-sharing is happening on social media, where women are historically more likely to be users," said Duggan.
"In terms of mobile, young people have always been early and eager adopters of new apps and platforms for sharing," she added.
