Netflix reaffirmed its dominance of the streaming video market on Tuesday, as its mixture of live sporting events, popular returning series - and singular moments, such as a football halftime performance by Beyonce - helped attract a record number of subscribers over the holiday quarter.

The company raised subscription prices across most plans in the U.S. and several other markets. It added 19 million subscribers in the fourth quarter of last year.

The streaming giant is upping the cost of its standard ad-supported tier to $7.99 a month in the U.S., up from $6.99, and the standard plan is increasing by $2.
