DirecTV Now is the latest online TV service to offer an alternative to cable or satellite packages that can easily cost about $100 a month.
Typical cable deals get you hundreds of channels, including the major networks, sports channels, niche options like the horror-focused Chiller and premium channels like HBO. Online services, individually, are cheaper, but you may need several to get everything you like to watch.
A sampling of some of the biggest internet TV options:

DirecTV Now joins Sling and PlayStation Vue as an online cable replacement. These can be cheaper than traditional cable, but not always by much. They're not as complete, as they don't provide broadcast networks ABC, CBS, Fox and NBC in all locations and sometimes lack a DVR. And you'll need an additional streaming gadget to watch on a TV set.

DISH'S SLING TV
Price: Starts at $20 a month.
Live offering: Two separate, "skinny" bundles of general-interest channels. Both cost less than $30, but each are missing some popular networks. A $40 service combines those. Add-on packs tailored to interests like kids and sports and premium channels like HBO cost extra.
On demand: No DVR, although it's coming for some users in December. There is on-demand video for some programs so you can catch up on missed episodes.
Restrictions: The $20 service allows just one stream at a time, the $25 one gets three. Only people in some cities can get broadcast networks, and CBS isn't available at all. NFL blackouts on mobile devices.

SONY'S PLAYSTATION VUE
Price: Starts at $30 a month. Starts at $40 if you live in Chicago, Dallas, Los Angeles, Miami, New York, Philadelphia and San Francisco, because there are more live broadcast feeds available in those cities.
Live offering: A core bundle of roughly 45 general-interest networks; bigger packages offer more sports, movies and some other channels. No Viacom networks like Nickelodeon, BET, Comedy Central or MTV.
On demand: A DVR so you can fast-forward through commercials, but shows expire after 28 days. Also on-demand episodes when they're available.
Restrictions: Only people in some cities can get broadcast networks live. Not all channels are available when you leave your home; neither are recorded shows.
