The OTA networks have affiliates in every market that get money from local advertising. If it were on feed nationally it wouldn't be a problem but it's not. You and I might see the same show but will see totally different commercials.
That's ridiculous. Just because Apple has a large user base doesn't mean they'll subscribe to a TV service. You can say that DirecTV has a potential user base of 300 million because their footprint covers the entire US.
