Compelling content is a key component in the successful adoption of 3D in the home. Now that you have, or are considering purchase of a 3DTV, here's where 3D programs are going to come from:

3D Blu-ray disc
At the moment the spigot's only open far enough for a trickle of 3D Blu-ray titles to reach consumers. The first, released in April 2010, was Twentieth Century Fox Home Entertainment's "Ice Age: Dawn of the Dinosaurs" followed by Universal's "Coraline" and Sony's "Cloudy with a Chance of Meatballs.” Other movies titles already announced for release this year in full HD 3D Blu-ray include Disney's "A Christmas Carol,"  Dreamworks’ "Monsters vs. Aliens" as well as the thriller “Piranha 3D,” the concert movie "PHISH 3D" and all three "Shrek" movies.

Going forward it helps, of course, that there will be plenty of 3D theatrical releases available for conversion to 3D Blu-ray. The New York Times film critic A.O. Scott recently noted "we find ourselves in the middle of what film historians may remember as the great 3D frenzy of 2010." In all, 18 3D movies opened in 2009, but more than three times that number - 56 - are scheduled for release this year including the fourth "Shrek" movie and "Toy Story 3".

For 2011, acclaimed director Martin Scorsese will give us "The Invention of Hugo Cabret," a children's story scheduled for theatrical release in 3D in December 2011. Thirty-three other films are planned for release in 3D next year including the fourth installment in the "Mission Impossible" movie franchise from Paramount Pictures. Fourteen 3D productions are already in the works for 2012 include "Men in Black 3" from Columbia Pictures and Twentieth Century Fox's "Ice Age 4: Continental Drift."

Television
According to new consumer research, 3D in the Home: Who, What, When, and Where from the Consumer Electronics Association (CEA) and the Entertainment and Technology Center (ETC) at the University of Southern California, two-thirds (67 percent) of those planning to buy a 3D-enabled TV within the next three years say they will be more likely to buy if they can receive and watch 3D television programs through an antenna, cable, satellite or fiber-to-the-home. 

They will soon be able to do just that. In a bid to capitalize on the emerging home TV audience for 3D, in March Cablevision became the first cable company to broadcast a live 3D sporting event to its subscribers. Cablevision carried a New York Rangers - New York Islanders hockey game in 3D, using a 1080i/30 format that required active shutter glasses. In April, Comcast and Cox followed with a 3D telecast of the Masters golf tournament, also using the 1080i/30 format. 3D coverage of the Masters proved to be an experience that's truly the next best thing to being there, as the wide open outdoor setting allowed viewers to see for the first time the elevation changes, undulations and other noticeable variations in course topography that makes the Augusta National course so challenging.

DirecTV has promised its viewers extensive 3D programming including movies, documentaries and events.

In June, DirecTV will debut four 3D channels: ESPN 3D and three of its own channels. The 3D picture format will be 1080i/30 and active shutter glasses will be required to view the 3D images. One of DirecTV's newly named 3D channels, N3D powered by Panasonic, will deliver 3D content from programmers such as AEG/AEG Digital Media, CBS, Fox Sports/FSN, Golden Boy Promotions, HDNet, MTV, NBC Universal and Turner Broadcasting System.

ESPN has announced they'll be starting up a 3D channel with 85 events planned in the first year, starting with the 2010 FIFA World Cup soccer tournament in June. Other events to be produced in 3D include X Games 16, 2010 college football, the ACC Championship, the 2011 BCS National Championship game and in 2011 college basketball and NBA games.

Discovery Communications has partnered with IMAX and Sony to create a dedicated channel that will broadcast 3D in the 1080i/30 HDTV format on a 24/7 basis. The new 3D network will feature content from genres that include natural history, space exploration, adventure, engineering, science and technology, motion pictures and children's programming. 

The YES Network, FSN Northwest and DirecTV will present the first-ever Major League Baseball telecasts in 3D on Saturday, July 10 and Sunday, July 11 when the New York Yankees take on the Seattle Mariners. DirecTV subscribers with 3DTVs will be able to receive the game within the YES network's broadcast footprint, which includes all of New York State and Connecticut, north and central New Jersey, and northeast Pennsylvania, as well as the FSN Northwest footprint, including the entire states of Washington, Oregon, Alaska and parts of Montana and Idaho.

Over the air broadcasting in the new 3D formats will have to await creation of standards for over the air 3D - none currently exist - and then development of a special 3D converter box and/or a TV firmware update.

PC Games
The tentacles of 3D extend beyond the TV set. You will also be able to watch 3D on your computer if the computer is equipped with a 3D-compatible video card - 3D gaming is supported by nVidia and AMD - and a 3D-enabled monitor, which are available from Acer, Alienware, LG, Samsung and Viewsonic, among others. Complete systems such as NVIDIA GeForce 3D Vision provide glasses and software to automatically transforms hundreds of PC games into full stereoscopic 3D right out of the box; whenever a compatible game is launched, the 3D trickery kicks in automatically.

Online
On the web YouTube has a dedicated 3D channel viewable using anaglyph glasses (limited to color anaglyph 3D because of bandwidth issues). Similarly, with a pair of red/blue filter anaglyph glasses you can go online and view NASA's "Mars in 3D" images courtesy of the Phoenix Lander's stereoscopic imager.

It is expected that within a year or two, a fast broadband connection will allow you to stream a 3D movie from content providers like Netflix, Vudu, and Amazon.
