One thing people should keep in mind is not to count services your already paying for when considering savings. For example I’ve had netflix and Amazon prime for several years and my internet wasn’t part of my satellite tv. So when we cut the cord we only added 10.00 month for Cricket on sling international and 130.00 a year for NHL the only sports we care for a total extra cost of 250.00 dollars saving 985.00 dollars a year which easily pays the one time cost of a antenna and the new tivo without fees
For decades, consumers who wanted just a few channels had to pay for all of them. Comcast or DirecTV couldn’t offer, say, MTV without also including Viacom’s less popular channels such as TV Land. While consumers wanted to pay for single networks on an a la carte basis, the industry fought attempts to break the bundle into smaller, less expensive pieces.
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.
