iTunes is attractive to Hollywood as a distribution medium, and is seen as a way to make more money from content otherwise thought to be difficult to sell in many cases.
"Making our television content available to iTunes consumers is an important step in our digital distribution strategy," said Simon Kenny, president of Warner Bros Digital Distribution.
"This deal fits perfectly with our philosophy of providing consumers with access to our world-class entertainment properties across the widest selection of platforms and devices available."
The video download service from iTunes has attracted some criticism from customers, notably for long download times and unimpressive video quality. But at US$1.99 a pop, itís hard to complain.
