People really arent joking when they talk about binge watching House of Cards. According to a study by Procera Networks, about two percent of all Netflix streaming subscribers in the US finished the series new season over its debut weekend. Based on Netflixs most recent user numbers, that means around 668,000 people watched the seasons 13 episodes across just three days. As usual, Netflix declined to release its viewership numbers, so the exact statistics cant be confirmed.
