Streaming video provider Netflix says that it has been sending lower quality video to mobile subscribers on AT&T and Verizon networks to help prevent them from surpassing data caps.
Increased consumption of video on mobile devices has led many Netflix members to worry about surpassing data caps, the company says.
So more than five years ago, the video service began sending a lower resolution feeds to members on mobile networks with data caps.
The issue came to light last week when T-Mobile CEO John Legere posted a video on Twitter saying that AT&T and Verizon customers get lower quality video from Netflix that T-Mobile users do.
A two-hour HD movie can eat up 6 Gigabytes of mobile data, but watching at lower resolutions can reduce data by as much as 90%.
