The stats came as market research firm Ipsos in North America published a new report, called The Twitter Effect: Understanding Twitter’s Role in TV Behaviours.
In this, Ipos claimed that 93% of Twitter users were likely to have a cable, satellite or fibre-optic subscription compared to 86% of non-users.
“What this translates into is that Twitter users are in fact watching just as much, if not more traditional content (i.e. broadcast and cable) as non-users. The most notable differentiator between the two groups is that Twitter users are more likely to also consume TV content on emerging platforms such as online SVOD services and content freely available on the internet,” said Ipsos.
The report also found that 69% of Twitter users watch full TV episodes on live TV at least once a week, compared to 59% for non-Twitter users. Some 66% of Twitter users also watched TV on YouTube compared to 40% for non-users, with 57% of Twitter users doing the same on Netflix weekly, compared to 39% for non-Twitter users.
