Hulu will pass the $1 billion mark in revenue for 2013, marking an increase of nearly one-third over its 2012 revenues. This according to a post last week on Hulu’s official blog. Since 2010, the television and movie-streaming service’s revenue has more than tripled, and revenues are up nearly $900 million since 2009. While the service now counts five million Hulu Plus subscribers as its base, it still trails rival Netflix by tens of millions.
