Netflix is preparing to launch its newest original series this month, "Marco Polo," which focuses on the life of the famous explorer, including his interactions with Kublai Kahn.

It's one of the most expensive TV series ever made, according to The New York Times, since it costs $90 million to produce 10 episodes. The only show with a higher budget is HBO's "Game Of Thrones."

But there's another reason "Marco Polo" is so important for Netflix. The company is hoping the series will appeal to international audiences as it expands, especially since Netflix holds the international rights to "Marco Polo."
