Are the "major broadcast networks" even the big dogs to compare yourself to now? It seems like the top-rated programs now are all on cable. Walking Dead, Game of Thrones, etc.
The major broadcast networks are who you compare yourself to if you want to talk about your reach. It only stands to reason that the free, over the air TV channels will have more viewers than a channel you have to pay to have the ability to view (cable), then pay more before you actually get to see their content (HBO). Two different metrics.
Kind of like how Apple touts how much money they're making from iOS and the App Store, while Google talks about how many devices are running Android. Android has a lower barrier to entry, while the iPhone has a greater profit margin. Two different metrics for two different demographics.
