Netflix Inc. has been lowering the quality of its videos for customers on most wireless networks across the globe for more than five years, The Wall Street Journal reported on Thursday.
This includes U.S. networks AT&T and Verizon Communications, the report said.
Netflix said the move was to "protect consumers from exceeding mobile data caps" as that may discourage future viewing, the WSJ reported.
Netflix's admission came after U.S. carriers AT&T and Verizon Communications last week were put on the defensive over accusations that they were downgrading the quality of Netflix videos.

Netflix said on its blog Friday that it will be introducing a data saver feature for mobile apps that will allow members more control over their data usage when streaming on mobile networks.
The feature is expected to be introduced in May.
Netflix didn't immediately return CNBC's email seeking comment, which was sent outside office hours.
