The NCAA Tournament is underway. Here’s how to watch it on TV and stream online.

First things first: Click here for our interactive NCAA men’s tournament bracket.

After being the first major sports events canceled last year when the coronavirus pandemic began, the NCAA’s men’s and women’s basketball tournaments are back. Here’s a viewer’s guide with what you need to know about how to watch all the games on TV and online, where the games will be played, who the announcers will be, and more.

We’ll start with the men’s tournament, and get to the women’s tournament later in the story.

A lot, starting with the fact that all the games are in Indiana in order to reduce travel. We are still in a pandemic, after all, as Duke and Virginia and Kansas can attest to.

Most of the games will be at venues in Indianapolis, with a few at Indiana University in Bloomington and Purdue University in West Lafayette. You’re going to see some games played at really cool old gyms. More on that later.

Another way the NCAA has reduced travel for teams is changing the days of the week on which games will be played. If you’re used to taking the third Thursday and Friday of March off work — or at least sneaking away from your desk to watch as many afternoon games as you can — get ready to adjust your schedule.

This year, all four First Four games are Thursday, March 18, starting at 5 p.m.; TBS and truTV will have two each. The first round starts Friday, March 19, and the second day of it is Saturday, March 20. The second round is Sunday, March 21 and Monday, March 22.

So the weekdays to clear out are a Friday and a Monday instead of a Thursday and a Friday.

The Sweet 16 games will be Saturday, March 27 and Sunday, March 28. The regional finals will be in prime time on Monday, March 29 on CBS and Tuesday, March 30 on TBS.

The Final Four will have its usual Saturday-Monday schedule, April 3 and 5, with all of those games on CBS.

We’ve got the full schedule of game times at the bottom of this article.

There are also more announcer teams than usual this year, including the NCAA Tournament debut for Tom McCarthy. The Phillies’ TV play-by-play voice has been a regular game-caller on CBS and CBS Sports Network in recent years, and now gets the call-up to the big stage. He’ll be paired with Avery Johnson, the former head coach of the Brooklyn Nets and the University of Alabama. Johnson has done TV work for ESPN in the past.

TV broadcasts of games are once again spread across CBS (24 games), TBS (20), TNT (12) and truTV (11).

Online streaming will mainly be through the March Madness Live website and apps for phones, tablets and connected TV devices like AppleTV, Roku, and Amazon Fire Stick. Streaming that way is free of charge with a login via your pay-TV provider.

But there’s a catch. While you can watch every game from all four TV channels on your computer, tablet, or mobile device, the CBS games won’t be available through the connected TV apps. Those streams will only be on Paramount+, CBS’ subscription streaming platform.

This catch has been around for a few years now, and it’s a headache for fans who like to switch between games to catch whichever one is the most dramatic at the moment.

On top of that, the March Madness Live AppleTV app quietly got rid of the ability to watch multiple games on one screen. Which means you need four separate screens to watch four simultaneous games, unless you have DirecTV (channel 205).

Nor will the NCAA’s online live highlights show, Fast Break, solve the problem. It will be available on phones and tablets, and if you can watch that way, it should be great. The show jumps around to all the best action from every ongoing game in real time.

But it won’t be available on connected TV devices. So, again, the only ways to watch CBS games if you don’t have cable or satellite TV are via an antenna, a Paramount+ subscription, or a subscription to a cable-like streaming platform such as YouTube TV.

By the way, if you subscribe to one of those streaming services, make sure to check what your subscription includes. Some of them don’t have all the channels — for example, fuboTV doesn’t have TBS, TNT, and truTV these days.

Another thing that hasn’t changed: Even though all of the games will be played in Indiana, the four regions of the men’s bracket are still called East, South, Midwest and West.

First Four: Mackey Arena in West Lafayette, and Simon Skjodt Assembly Hall in Bloomington.

First Round: Mackey Arena, Simon Skjodt Assembly Hall, and four venues in Indianapolis: Bankers Life Fieldhouse (home of the NBA’s Pacers), Butler University’s Hinkle Fieldhouse, Indiana Farmers Coliseum, and Lucas Oil Stadium (home of the NFL’s Colts, with two courts set up on the football field).

Second Round: Bankers Life Fieldhouse, Hinkle Fieldhouse, Indiana Farmers Coliseum, and Lucas Oil Stadium.

Sweet 16: Bankers Life Fieldhouse and Hinkle Fieldhouse.

Elite Eight, Final Four and championship game: Lucas Oil Stadium.

Fans will be allowed in the stands, with the total number of people in the building set for 25% capacity. Mask-wearing and physical distancing will be required.

If you’re a hoops junkie, you’ll love Mackey Arena, Assembly Hall, and especially the grand old brick-and-steel Hinkle Fieldhouse.

The first four groups listed will also call regional finals.

There will be two studio crews. From Turner’s studios in Atlanta, Ernie Johnson will host with Charles Barkley, Andy Katz, Candace Parker, and Kenny Smith. And from CBS’s studios in New York, Greg Gumbel and Adam Zucker will host with Seth Davis, Clark Kellogg, and Wally Szczerbiak.

Glad you asked. ESPN remains the home of the women’s tournament, and this year it’s putting some games on ABC. It will be the first time since 1995 that women’s tournament games are airing on over-the-air network TV.

The tournament’s first round is Sunday, March 21 and Monday, May 22, with games on ABC (Sunday only), ESPN, ESPN2, and ESPNU. The second round is Tuesday, March 23 and Wednesday, March 24, with games on ESPN, ESPN2, and ESPNU.

Action returns to ABC for the Sweet 16 on Saturday, March 27 and Sunday, March 28, with games also on ESPN2 on the Saturday and ESPN on the Sunday.

From there on, all the games are on ESPN in prime time. The regional finals are Monday, March 29 and Tuesday, March 30; the Final Four is Friday, April 2; and the championship game is Sunday, April 4.

All the games in the women’s tournament will be played in and near San Antonio. The Alamodome will host games in every round start to finish, with two courts at times on the football field-sized floor.

Other venues include the University of Texas’ Frank Erwin Center in Austin and Texas State University’s Strahan Arena in San Marcos for the first round; and St. Mary’s University’s Bill Greehey Arena and the UTSA Convocation Center in San Antonio for the first and second rounds.

The four regions of the bracket are named for San Antonio landmarks: Alamo, Hemisfair, Mercado and River Walk.

Attendance will be up to 17% of each venue’s capacity, with mask-wearing and physical distancing required.

On the men’s side, Drexel (a No. 16-seed as CAA tournament champion), Villanova (a No. 5 seed at-large), and Rutgers (a No. 10 seed at-large). On the women’s side, Drexel (a No. 14 seed as CAA tournament champion), Lehigh (a No. No. 13 seed as Patriot League tournament champion), and Rutgers (a No. 6 seed at-large).

The Dragons’ men’s team is one of this March’s best stories, as it’s their first time in the Big Dance in 25 years.
