Broadcast rules don't apply to cable channels anyway. This was the decision of someone who calls the financial shots for Court TV. They guarantee an advertiser that their commercial will be seen at 4:20PM and it will be shown at 4:20PM.

Then again, Court TV went from being a news channel to being an entertainment channel several years ago. When it hits 3PM (PT) regardless of what is going on in court they always dump it for for old cop shows.
