Netflix Inc. (Nasdaq: NFLX)

Netflix Inc. (Nasdaq: NFLX) delivered big news this week to those doubting its stock can keep up its meteoric rise: It's going global.

The online video service announced Tuesday it will expand into 43 countries in Latin America and the Caribbean, giving investors another reason to bet on its long-term growth.

The move means Netflix has access to a brand new avenue for profit, instead of focusing solely on the developed North American market.

The announcement pushed Netflix shares up about 8% Tuesday. Netflix's phenomenal 1,000% price jump since 2008 - 68% this year alone - has short sellers in a frenzy, thinking the company must be due for a significant pullback.

But as we told you in May, those doubters should reconsider their stance.

Netflix has revolutionized the way people watch movies, and is transforming the way people watch TV. Now it's implementing its media innovations on a worldwide scale.

Netflix joins the growing group of U.S.-based companies like PepsiCo Inc. (NYSE: PEP) and General Motors Co. (NYSE: GM) in targeting emerging-market growth, and analysts say the ventures will pay off.

"I like the fact that Netflix is growing aggressively into emerging economies because that's clearly where the spending patterns show money is going to be," said Money Morning Chief Investment Strategist Keith Fitz-Gerald. "I think the latest estimates show that there's more than $1 trillion expected to flow into developing economies this year."
