Netfllix shares jumped 7.6% as of mid-day after the company said it will offer its Web streaming service through Latin America and the Caribbean later this year. Investors are hoping that audiences in other countries will respond as enthuiastically as U.S. consumers have to the home video company’s service. Netflix had 22.8 million domestic subscribers at the end of March. But a lot depends on how much the international services will cost — and whether studios provided Netflix with licensing rights to offer the same movies and TV shows abroad that it provides to U.S. subscribers.

Netflix doesn’t offer many details about its plans. Here’s the release:

Netflix, Inc. (Nasdaq: NFLX), the leading Internet movie subscription service, today announced it will expand to 43 countries throughout Latin America and the Caribbean later this year, offering unlimited TV shows and movies streaming instantly over the Internet to TVs and computers for one low monthly subscription price. Netflix has been streaming to U.S. members since 2007, adding the service in Canada last year.

Upon launch, Netflix members from Mexico, Central America, South America and the Caribbean will be able to instantly watch a wide array of American, local and global TV shows and movies right on their TVs via a range of consumer electronics devices capable of streaming from Netflix, as well as on PCs, Macs and mobile devices.

Members in the region will be able to access Netflix in Spanish, Portuguese, or English, depending on their preference.
