Earlier in the week, Netflix announced plans to raise its subscription price. The company said the new pricing in the U.S. will be phased in for existing members of Q1 and Q2.

Netflix said that in the U.S. it gets about 10% of television screen time. It didn’t seem overly concerned with the rush of competitors coming into the streaming business.

“There are thousands of competitors in this highly fragmented market vying to entertain consumers and low barriers to entry for those with great experiences,” the company said. “Our growth is based on how good our experience is, compared to all the other screen time experiences from which consumers choose. Our focus is not on Disney+, Amazon or others, but on how we can improve our experience for our members.”
