Where to Watch March Madness Online (and on Mobile and On-Demand)

Let’s be honest. This is the most wonderful time of the year. March Madness, baby! The NCAA Men’s College Basketball Tournament is back!

Once you’ve filled out your bracket and given $5 to the office pool, all that’s left to do is watch the games. We can’t do anything about them airing during office hours, but between online, on mobile, on demand and on TV, you have more options than ever to catch all the action. There’s a lot out there, so we’ve rounded them all up into one helpful guide.

ONLINE Your main source of March Madness online will be through NCAA.com (CBSSports.com is also a good starting point). From there you’ll be able to watch all 63 games for free in the brand new high-quality video player. Bonus, the player will have Facebook functionality built in, so you can send out status updates live while you’re watching the game.

If you’re too lazy to type in NCAA.com into your browser, there’s a good chance you’ll be able to watch the games at one of the many sites you already enjoy. CBS Sports is distributing March Madness to 300 different sites including Facebook, MySpace, YouTube and ESPN. Links on these pages will pop up the player so you can stay on the page you’re on.

ON MOBILE Want to watch your games on the go? CBS Sports now has a new March Madness on Demand application for the iPhone and iPod Touch that will stream the entire tournament live. The app will also provide tournament bracket updates and allow you to click directly from the brackets to live video.

The only bummer? The tournament will be streamed over Wi-Fi, not 3G, so you won’t be able to watch too far from a friendly wireless network. The March Madness app is available now and costs $4.99.

If you don’t have an iPhone, other AT&T handsets will offer the games live to MediaFLO subscribers.

ON DEMAND If you missed the game and want to watch highlights, there are a ton of on-demand choices out there. CBS has partnered with 20 different outlets, including Comcast, DirecTV, Verizon FiOS, and Charter, to deliver the NCAA VOD: The Best of March Madness, featuring HD highlights from throughout the tournament, free of charge.

Games from the Final Four will also be available for purchase the day after they are completed for $1.99 each at iTunes.

So get ready, get your brackets (The New York Times is giving away Amazon Kindle 2.0s for winners of its brackets) and get set to watch more March Madness than ever before.
