Despite the earnings gain, Netflix is raising the price of its monthly service for new subscribers. Current subscribers will be grandfathered for a non-specified (but characterized as "generous") time period. So if you're watching House or Titanic, or some of the other new titles added recently, you won't notice any change in the $7.99 per month that you are paying now.
If you are thinking about subscribing to Netflix, you could end up paying $1 or $2 more than the current rate. Netflix CEO Reed Hastings says that Netflix needs the added revenue to obtain more content and to improve the streaming experience.
