Olympics Live Stream 2012: When to Watch Biggest Events on Day 4

One of the biggest (and best) changes that NBC has made to the 2012 London Olympics is streaming virtually everything online. 

In this day and age, where almost everything is done online and more frequently we are only glancing at the television screen, it was a smart, logical way to go. The network previously did it with the Super Bowl in February to great fanfare. 

With day four of the Olympics bringing several top stars to the table, you have to know when to find all the action that you can stream while you are at work. 

Here is a look at the biggest events taking place on Tuesday in London and when you can watch it. 

(Note: Streaming events can be found at NBC Olympics by clicking here.)

Judo: Men's 81kg and Women's 63kg Medal Rounds

Start Time: 9:00 a.m. ET

If you haven't been following Judo at the Olympics, you really owe it to yourself to check it out. Even if you don't want to watch all of it, make a point to check out the medal rounds on Tuesday. 

The sport is a light version of mixed martial arts, with more emphasis on the mental side of things. You have to be smart and know when to attack before just diving in, like you would in MMA. 

It is a fun event with a lot of action, and you will see someone win a medal make sure you check it out. 

Swimming: Men's 200-Meter Butterfly, Women's 200-Meter Freestyle Finals

Start Time: 2:30 p.m. ET

Everyone knows that swimming is one of the biggest and most important events of the Olympics. Ryan Lochte, in particular, has become a fascinating character to watch this year. 

Lochte is one of the best swimmers in the world, yet he still feels a need to validate himself as someone on the same level with Michael Phelps. 

Given that Phelps isn't in this particular event, Lochte has a great chance to stake his claim to the medal throne. 

Water Polo: Six Preliminary Men's Matches

Start Time(s): 5:00 a.m. ET, 9:10 a.m., 1:20 p.m.

Despite not being a marquee Olympic event, Water Polo is one of those fun events that should get a lot more attention than it does. It requires tremendous skill, athleticism and intelligence to be successful. 

With six matches in the men's preliminary rounds, there will be plenty of chances to catch up on all your water polo action before getting into the nitty gritty of the event.
