we derive revenues from services consisting solely of streaming content offered through a subscription plan priced at $7.99 per month. In the Domestic DVD segment, we derive revenues from our DVDs-by-mail subscription services. The price per plan for DVDs-by-mail varies from $7.99 to $43.99 per month based on the number of DVDs that a subscriber may have out at any given point. Customers electing access to high definition Blu-ray discs in addition to standard definition DVDs pay a surcharge ranging from $2 to $4 per month for our most popular plans.

In July 2011, in the United States, we introduced DVD only plans and separated unlimited DVDs-by-mail and unlimited streaming making it necessary for subscribers who opt to receive both DVDs-by-mail and streaming to have two separate subscription plans. As subscribers were able to receive both streaming and DVDs-by-mail under a single hybrid plan prior to the fourth quarter of 2011, it is impracticable to allocate revenues to the Domestic streaming and Domestic DVD segments prior to the fourth quarter of 2011.

In the International streaming segment, we derive revenues from services consisting solely of streaming content offered through a subscription plan priced at approximately the equivalent of USD$7.99 per month. In September 2010, we began international operations in Canada. We expanded to Latin America and the Caribbean in September 2011 and the UK and Ireland in January 2012. Until we reach our goal of global profitability, we do not intend to launch additional international markets.



The $1,042.0 million increase in our consolidated revenues was primarily due to the 44.6% growth in domestic revenues with the increase in international revenues contributing to 7.6% of the increase year-over-year. Domestic revenues increased $962.7 million as a result of the 49.1% growth in the domestic average number of unique paying subscribers driven by new streaming subscriptions. This increase was offset in part by a 3.0% decline in domestic average monthly revenue per unique paying subscriber, resulting from the popularity of the unlimited streaming subscription (introduced in November 2010) and a decline in the percentage of unique paying subscribers electing both a streaming and a DVD subscription following the pricing changes in the second half of 2011. During the year ended December 31, 2011, 73.6% of our new gross domestic unique subscribers chose only an unlimited streaming plan which is priced at $7.99 per month and we expect that this percentage will grow in future periods. At December 31, 2011, 88.9% of our total domestic unique subscribers had a streaming subscription while less than half (11.1 million) had a DVD subscription.

International revenues increased by $79.2 million reflecting a full year of service offering in Canada as well as our launch in Latin America and the Caribbean.

The $492.4 million increase in our consolidated revenues was primarily a result of the 40.9% growth in the domestic average number of unique paying subscribers arising from the continuous improvement to our customer experience which in turn, drove consumer awareness of our service benefits.
