Its top-tier plan, which allows streaming on four screens in high definition, will be raised to $15.99 from $13.99 per month, while fee for its basic plan will rise to $8.99 from $7.99.

The price hikes will be applied to all existing members over the next few months and to all new members immediately, Netflix said in a statement.
