Almost one-third of Roku viewers in US watch in groups: study

Group activity: A new study shows 27% of all viewing on a Roku device is made up of two or more people.

Television networks and advertisers got an early holiday gift from ratings agency Nielsen and video streaming provider Roku Inc after a joint study showed 27% of all viewing on a Roku device is made up of two or more people. 

For advertisers contending with increasing concerns about whether people are actually viewing their ads, the findings show that they can approach buying ads through devices that stream video like Roku, known as over the top (OTT) platforms, in a similar way that they approach buying television spots, said Scott Rosenberg, vice president of advertising at Roku.
