A TV network's product is television content, their monetization strategy is advertising. The delivery mechanism is cable / airwaves.
Sure there are secondary economic effects and markets that complicate the picture. But the basic business model of a television network isn't all that different than a regular company that sells their products directly.
If that's true, then what's their programming called?
Programming is their product, and customers buy it by paying attention (or to netflix, hulu, comcast, etc more directly). Attention is the currency, and ads let them exchange attention for USD.
So AMC and HBO are making different things? No, of course not. They both produce content and distribute it through cable networks. One of them charges advertisers to deliver the product to viewers, while the other one charges the viewers directly.
To be fair, if you're an advertiser, then the product is eyeballs. But if you're a pair of eyeballs, then the product is the content. They're not mutually exclusive. Same with google. If you're a searcher, then the product is results. If you're an advertiser, then the product is relevant searchers.
