When is the Sweet Sixteen?

The Sweet Sixteen begins on Thursday, March 24. Current matchups for Thursday include No. 4 Arkansas vs. No.1 Gonzaga but the finalized matchups and game times -- including if No. 11 Michigan will play No. 2 Villanova or No. 7 Ohio State -- won't be known until after Sunday's action concludes. 

Friday's Sweet Sixteen games include No. 4 Providence vs. No. 1 Kansas and No. 8 North Carolina vs. No 4. UCLA. No. 15 Saint Peter's will be playing on Friday as well, though as with Michigan we won't know who they will face until after today's game between No. 3 Purdue and No. 6 Texas. 

Where is the Final Four taking place?

The Final Four and national championship game will take place in New Orleans at the Caesars Superdome and will air on TBS.

Which channels will air March Madness games?

Games for the NCAA tournament will air on CBS, TBS, TNT and TruTV.

Per the NCAA, here is the breakdown of where you can find games: 

• CBS will broadcast 21 games throughout the tournament, including the Elite 8, Sweet 16 and first and second rounds.
• TBS will televise 21 games, including the National Championship, Final Four, Elite 8, Sweet 16 and first- and second-round games.
• TruTV will air a total of 13 games, including the First Four and the first and second rounds.
• TNT will televise 12 games, including first- and second-round matchups.

Three of the streaming services -- YouTube TV, Hulu Plus Live TV and DirecTV Stream -- offer all four of the above channels needed to catch all of the madness this month.

You can also stream the games live at with NCAA March Madness Live. There is a free three-hour preview, but then you'll need to log in with a TV provider to prove you are a pay-TV subscriber. You can also watch the games broadcast on CBS with Paramount Plus... but that's less than ideal because the Final Four games and national championship game will be shown on TBS this year, not CBS.

What channel is TruTV?

You'll need to locate TruTV on your channel lineup for the first two rounds of the tournament if you don't want to miss any of the games and potential buzzer-beaters. Here's where you can find it on some of the biggest cable and satellite providers:

Can I watch for free?

Yes, you can. There are two ways, but neither will get you through the entire tournament by itself.

The March Madness Live app and website offers a free, three-hour preview, after which point you'll need to prove you are a pay-TV subscriber. 

The other way is to sign up for a live TV streaming service. Each of the major five services offers a free trial. YouTube TV, Hulu With Live TV and FuboTV offer seven-day trials, while DirecTV Stream gives you five days and Sling TV has the shortest trial with three.

YouTube TV costs $65 a month and includes CBS, TBS, TNT and TruTV to watch every game of March Madness. Plug in your ZIP code on its welcome page to see what live, local networks are available where you live. Read our YouTube TV review.

Hulu With Live TV costs $70 a month and includes CBS, TBS, TNT and TruTV. Click the "View all channels in your area" link on its welcome page to see which local channels are offered in your ZIP code. Read our Hulu With Live TV review.

DirecTV Stream's basic, $70-a-month package includes CBS, TBS, TNT and TruTV. You can use its channel lookup tool to see if you get a live feed of CBS and the other local networks in your ZIP code. Read our DirecTV Stream review.

Sling TV is a poor choice for watching March Madness because it does not include CBS. Its $35-a-month Blue plan includes TruTV along with TBS and TNT. Read our Sling TV review.

FuboTV costs $65 a month and includes CBS, but not TBS, TNT or TruTV. With the Final Four games and national championship game on TBS, FuboTV is not a good pick for college basketball fans. Click here to see which local channels you get. Read our FuboTV review.

You can stream every game of March Madness on the NCAA's March Madness Live site or app. You can watch for three hours for free, but then you will need to log in to prove you have a pay TV subscription that includes the channels that televise the tournament. It should be noted that in addition to cable and satellite providers, you can use a YouTube TV, Hulu With TV, DirecTV Stream or Sling TV subscription to access March Madness Live. (FuboTV is the lone exception among the live TV streaming services because it doesn't offer any of the Turner-owned stations.) 

Latency is an issue with any streaming service and particularly with live sports, where you might also be following along on Twitter and could see a final score before the game actually ends. The NCAA says this year's streams will offer a 20% latency improvement compared to last year's. While that is welcomed, March Madness Live streams will likely still be behind cable and satellite TV and could also trail streams from YouTube TV and the other live TV services.
