The debut season of Netflix’s first original series “Lilyhammer” is now available on demand to all Netflix “Watch Instantly” subscribers. All eight episodes of the series’ first season can be streamed beginning Tuesday, and the show is available in high definition. Lilyhammer is the first in a string of original content Netflix is working on in an effort to create an all-inclusive online-only network that will truly pose a real threat to traditional pay TV networks. The show features Steven Van Zandt of “The Sopranos” fame, who stars as a relocated New York City gangster trying to make a new life for himself in a small town in Norway. Netflix is working on more original content that will launch this year, including a new season of “Arrested Development” and “House of Cards,” starring Kevin Spacey.
