Netflix, which began as a mail-order DVD service but is now producing award-winning original content alongside its offering of older shows and movies, launched in 2007. Now, 70 million subscribers pay a monthly fee for unlimited service.
"Today you are witnessing the birth of a new global Internet TV network," co-founder and chief executive Reed Hastings said at the Consumer Electronics Show in Las Vegas.
"With this launch, consumers around the world – from Singapore to St. Petersburg, from San Francisco to Sao Paulo - will be able to enjoy TV shows and movies simultaneously - no more waiting."
"While you have been listening to me talk, the Netflix service has gone live in nearly every country in the world except China, where we hope to be in the future."
Netflix noted in a statement that it "continues to explore options for providing the service" in China, the world's most populous country, where the government censors online content it deems to be politically sensitive.
Other countries or markets without the service are Crimea, North Korea and Syria due to US government restrictions on American companies, Netflix said.
While English is the main language for most of the new markets, Netflix said it has added support for Arabic and Korean, along with simplified and traditional Chinese to the 17 languages it now uses.
