Since the first high-definition DVDs came on the market in early 2006, Netflix has stocked both formats.
But Netflix said that the industry has stated its clear preference for Blu-ray and that it now makes sense to initiate the transition to a single format.
"The prolonged period of competition has prevented clear communication to the consumer regarding the richness of the HD experience versus standard definition, " said Ted Sarandos, chief content officer at Netflix.
"We are now at the point where the industry can pursue the migration to a single format, bringing clarity to the consumer and accelerating the adoption of high-def.
"We expect that all studios will publish in the Blu-ray format and that the price points of high-def DVD players will come down significantly."
While only a portion of Netflix subscribers have elected to receive high-def DVDs, a majority of those subscribers have chosen Blu-ray over HD-DVD, according to the company.
Netflix said that it will acquire no new HD-DVDs and that its current inventory would continue to rent until the discs' natural life cycle takes them out of circulation in the coming months.
