Actually no, the term 'blackout' is still valid - with or without Sunday Ticket. If a game is blacked out in a specific viewing area (I believe it is within 75 miles of the stadium), it is blacked out on all televisions in that area regardless of how the signal is delivered, and whether it is a home or a business. Doesn't matter if you are receiving your signal via cable, dish, or rabbit ears, and it doesn't matter if you're trying to watch at home or watch at the local pub that has Sunday Ticket.
For example, people in the Jacksonville area couldn't just go to a local sports bar to see a Jaguars home game last year. The bars that had Sunday Ticket could access every game except for that Jaguars home game that didn't sell out. If you're outside that 75-mile radius you can pick up every game regardless of whether it sells out or not, but not if you live locally.
