This script will use the show and episode names of a single selected TV Show track in iTunes to search the IGN.com website for that episode's page and then parse that page for the original airdate and network. You can then either open IGN.com's page for the episode or add the info to the selected TV Show's comment field. Note that results using this version are not always fruitful.
"Get Airdate and Network" will attempt to get the original airdate and network information from IGN.com for the selected TV Show track. You can then either view the IGN.com episode page or add the airdate and network text to the track's comment field.
