In the United States, NBC is the network televising the Summer Games. The company will put on nearly 7,000 hours of content and use 11 networks to highlight the big events. As the Washington Post noted, "it's more or less all Rio, all the time" on NBC, with coverage every day from 10 a.m. to 5 p.m. and 8 p.m. to midnight. Some events will air on Telemundo, the NBC Sports Network, the Golf Channel and USA Network, as well.

No cable, no problem — TechHive recommends signing up for a service like Sling or buying a digital antenna to get your Olympics fix.

"We expect consumption of the Olympics to soar ... on both our web and mobile apps. These are optimized for viewing," NBC Olympics President Gary Zenkel told Sports Video Group. "It's there every second. If you like tennis, you can watch three courts at one time. And then, if you're just away from your television and you want to catch what's on NBCSN, it's there as well."

After the Olympics are the Paralympics, which will be held in Rio from Sept. 7 to 18. Check out that schedule here.
