A new report seems to confirm what you could probably already guess: that, like every other device you own, some TV streaming devices are collecting lots of data about what you do.
The report comes from Princeton University and the University of Chicago, and focuses on two platforms: Roku and Amazon Fire TV. To see what apps on these two services tracked, the people behind the study created what they call “smart crawlers.”
They essentially did the same thing humans would do — install apps (the top 1,000 on each device) and watch videos — while taking a look at the data that was collected any time an ad was shown. You can guess where this is going.
