MLB Network is an American television specialty channel dedicated to professional baseball. It is primarily owned by Major League Baseball. Comcast, DirecTV, Time Warner Cable and Cox Communications have minority ownership of the new network, with MLB retaining a controlling two-thirds share. The channel's headquarters and studios are located in the Secaucus, New Jersey facility which formerly housed MSNBC's studios. By 2015, revenue from cable subscriber fees and advertising is projected to exceed $210 million, with a net value over $1 billion. Tony Petitti, former executive producer of CBS Sports, was named the network's first president.
Despite pioneering league-owned programming with the short lived over-the-air The Baseball Network, Major League Baseball became the fourth major North American professional sports league to launch its own 24-hour channel. NBA TV dates back to 1999, the NHL Network to 2001 (though not in the United States until 2007), and the NFL Network to 2003. However, MLB Network is carried in the most households of these four networks, largely because of the financial participation of the cable systems.
MLB Network soft-launched on December 16, 2008 with a rolling automated loop of archival programming and promotions for the network for cable systems that carried the network's transmissions leading up to the January 1 launch. The channel fully launched at 6 PM EST with the premiere of Hot Stove.
The network has signed contracts with 36 cable and satellite carriers. In a deal that was pioneered by other sports league owned channels, MLB tied carriage of the MLB Network to the ability to carry the popular out of market MLB Extra Innings package. In return, cable and satellite providers were offered a minority share of the new network. Two major television providers that are not currently carrying the channel are AT&T U-Verse and Dish Network, leaving DirecTV with satellite exclusivity. Dish Network has been in an ongoing carriage dispute about MLB Extra Innings since the end of the 2006 season. 
On March 26, 2010, it was announced that satellite radio station MLB Home Plate will be rebranded to MLB Network Radio which will simulcast some MLB Network programs such as MLB Tonight. The switchover began on April 4, the first day of the 2010 MLB season. 
To date, no announcements have been made about MLB Network availability in Canada, home of the Toronto Blue Jays. Network officials have been in contact with Blue Jays owner (and Canada's largest cable company) Rogers Communications about making MLB Network available in Canada, but emphasized prior to the channel's launch that a deal was not imminent.
In August 2008, Rogers secured Canadian Radio-television and Telecommunications Commission (CRTC) approval for a Canadian digital channel tentatively called "Baseball TV", which has not yet launched. This license could be used to launch a localized version of MLB Network with domestic advertising and additional Canadian content, along the lines of NBA TV Canada, which is owned by the parent company of the Toronto Raptors but uses much of the content of the league's U.S. channel NBA TV. It appears Rogers would prefer this approach. An alternative would be for MLB and a sponsoring cable or satellite company (such as Rogers) to seek separate CRTC approval to import the U.S. channel directly; this was the approach taken with NFL Network.
MLB Network HDEdit
MLB Network HD is a 720p high definition simulcast of MLB Network, which launched simultaneously to the regular channel. After much discussion, MLB Network decided to use the 720p format instead of 1080-line-interlace because it believes 720p shows the motion of baseball more accurately and will degrade less when recompressed by cable operators to save bandwidth. As Mark Haden (VP of engineering and IT of MLB Network) says: “That's our best shot of maintaining quality to viewers.” All studio programs and original shows are shot in HD, as well as all self produced games such as those of the 2009 World Baseball Classic and Thursday Night Baseball, as well as simulcasted locally produced games on Saturday Night Baseball. The network is also currently remastering 30 World Series Films in high definition.  Also during MLB Tonight the channel shows exclusive live HD look-ins to games in progress via its local channel. Programs not available in HD originally have unique stylized pillarboxes: brick walls reminiscent of an older baseball stadium, with the MLB Network logo in the middle. Beginning on March 27, 2009, pillarboxes with a more generic design were used with some programming: solid blue bars with the logo in the middle. The brick wall design pillarboxes continue to be used at times as well.
The 720p format is also used by affiliates of regional sports network Fox Sports Net HD, which holds the rights to local game coverage of several teams. MLB national broadcast partners Fox HD and ESPN HD are also in 720p.

Live game coverageEdit
MLB Network airs several live games a week. All games are subject to local blackouts and therefore two games are offered each day.

The show has updates, highlights, news, and analysis. The original plan was also to feature exclusive live look-ins using their own permanent HD cameras with shots not available on any of the channels covering the game; however, MLBN has decided to use "ballpark cam" only before and after games. Live cut-ins simulcast from the station covering the game.

The Secaucus-based studios have two main sets, named after famous players. "Studio 3", named in honor of Babe Ruth, serves as the home plate for all studio programs, while "Studio 42", honoring Jackie Robinson, is a half-scale baseball field where demonstrations by the network's analysts take place. The studio includes seating for over 125 people, and a real-time out of town scoreboard based on those similar to PNC Park, Citizens Bank Park and Citi Field.
The network had planned to launch permanent studios from a new tower in Manhattan's Harlem neighborhood by 2011.  However due to the 2008 financial crisis, the building project was scaled back and later canceled in late November 2008.
