Apple is giving itself a pat on the back today, with the announcement that it has officially sold more than 200 million episodes of TV shows via iTunes, one million of which are HD episodes that sold in the short one month period they've been available. The number pales compared to the most recent 5 billion songs milestone, but is a clear indication that Apple is becoming a major player in the video download market.

The company also announced that iTunes now features HD shows from all four major networks - ABC, CBS, Fox and NBC - on top of their standard-definition offerings, completing a catalog of over 30,000 TV episodes and over 2,500 films. If you haven't shopped at iTunes for TV episodes yet, they'll run you $1.99 for a SD episode, and $2.99 for HD shows.
