The market is full of streaming devices and sticks that offer viable cable TV alternatives. Some of the more popular devices are Roku, Google Chromecast, Amazon Fire TV, and Apple TV. Investigate each option to compare prices and offers and see what works best for the shows and needs you have. These are the splurges that may actually end up costing more than you thought.
But cable providers didn't factor in that the internet they provide would become their worst enemy via access to streaming video. Services like Netflix, Hulu, and Amazon Video are the most well-known names in what's become known as "cord cutting"—doing away with pay TV and using over-the-air (like the old days) or internet-based services to get all your "television" programming. That means no more paying a huge monthly fee for thousands of hours of TV you don't watch (in theory). Instead, you pay individual services for a la carte programming. It's a lot like paying for just what you watch. Almost.
Verizon FiOS TV: Verizon's FiOS fiber television service is available in a number of states along the eastern seaboard and in Oregon and California. The company shook up the pay TV industry in 2015 by launching its custom build-your-own package, which allows customers to choose themed channel packs, similar to Dish's Flex Pack. You can see what channels they offer through our channel guide to Verizon FiOS. You can also bundle FiOS TV with FiOS high-speed internet.
The question of "when does it make sense?" can easily be rephrased as "how much money can I save?" and one of the biggest factors will be the price difference between combined internet and TV service or just internet. These are also the options that vary the most widely based on where you live, and the availability of promotions or contracts that can keep prices down for a short time.
