It's March Madness, even if you don't care about college basketball.

Beyond the hard-court dribbles later this month, there are plenty of companies circling important dates. Here are a few of the days that I plan to approach with eyes wide open.

March 2
TiVo (Nasdaq: TIVO) is set to make a major announcement in New York City on Tuesday. When you issue media invites that claim "Inventing the DVR was just a warm up," you're setting the bar of expectations pretty high.

TiVo sorely needs to live up to the hype. Despite the litany of partnerships and successful patent-protecting cases, the company continues to ooze subscribers.

It's not necessarily TiVo's fault. The growing options for online on-demand streaming have quieted the urgency of recording a show the moment it airs. For TiVo's sake, let's hope tomorrow's introduction is either mind-blowing innovation or a time machine for it to get back to a point when the playing field wasn't so level.

March 17
Beyond the green-beer revelry of St. Patrick's Day, Nike (NYSE: NKE) steps up for its quarterly report.

The financials will matter, of course, but the meaty questions during the company's conference call may pertain to the footwear and apparel giant's loyalty to Tiger Woods. A few sponsors have made a clean break from the disgraced golfer, but not the sultan of swoosh.

"When his career is over, you'll look back on these indiscretions as a minor blip, but the media is making a big deal out of it right now," Nike CEO Phil Knight said shortly after the scandal broke.

Woods' recent apology may soothe some critics, but one has to wonder how long Nike will continue to sponsor him if he doesn't return to the greens (and not of the St. Patrick's Day variety).

March 23
This should be the moment of truth for Netflix (Nasdaq: NFLX) and Coinstar (Nasdaq: CSTR). Time Warner's (NYSE: TWX) The Blind Side comes out on DVD, and Netflix and Coinstar's Redbox have agreed to hold back on making it available for another four weeks.

Time Warner feels that this window will help stir up sales, as it claims that it moves 75% of its DVD copies during the first 28 days on the market. Netflix and Coinstar will be getting price breaks for agreeing to the tiered strategy, but what will it mean for how couch potatoes perceive the two services?

The Blind Side was one of last year's biggest box office hits, and demand will only get healthier if the film fares well during this month's Academy Awards. Netflix has already kept The Invention of Lying and Time Traveler's Wife from its subscribers under similar Time Warner windows this year, but this is the first time that a bona fide blockbuster will be available through DVD rental chains and video on demand but not through Netflix queues.

March 25
Consumer electronics superstore Best Buy (NYSE: BBY) checks in with its holiday quarter results. Beyond the fact that Best Buy is an active recommendation in three of our newsletter services, Best Buy is a great proxy across a wide spectrum of gadgetry trends.

Who has the hot smartphone? Did video game sales pick up? Is 3-D television for real? Best Buy doesn't break down its results to answer these questions, but you never know what deep-diving queries will be posed by analysts on the call.

March 28
Is Nintendo (OTCBB: NTDOY.PK) ready to make the leap into more functional consumer gadgetry? It releases its DSi XL in North America on March 28.

The handheld gaming device features a screen that is 93% larger than the current model. The meatier display is opening the door for Nintendo to make a run at the booming e-book market. One of the first available titles is a collection of classic novels, and the built-in Wi-Fi connectivity will make digital delivery of books, newspapers, and magazines a breeze.

There are limitations here, so this may not be a Kindle or iPad slayer, but the $189 price point should turn heads.
