MLB.com is the official site of Major League Baseball. MLB.com is a source of baseball-related information, including baseball news, statistics, and sports columns. MLB.com is also a commercial site, providing online streaming video and streaming audio broadcasts of all Major League Baseball games to paying subscribers, as well as "gameday", a near-live streaming box score of baseball games for free. In addition, MLB.com sells official baseball merchandise, allows users to buy tickets to baseball games, runs fantasy baseball leagues (both free and paid), and runs auctions of baseball memorabilia.
MLB.com also contains the full, unabridged, official rules of the game, which can be useful for researching the rarely-invoked rules for unusual occurrences.
Normal blackout restrictions apply to games, and other countries may have blackout restrictions as well (see below.)
The costs of subscription depend on the quality the user will want to view, and the timing of payment:

|---|---|---|---|
| Monthly | $19.95 | $14.95 | Not available as a subscription |
| Yearly | $109.95 | $79.95 | $14.95 |
Mosaic is a downloadable program which provides features not available when streaming through a web browser. It is only available to subscribers of MLB.tv Premium. Live games are shown, and on-demand games are available for a period of two days previous to the current date.
Mosaic allows you to show multiple games at once, and provides the following viewing modes:
When set on one main game, team information is shown to the right hand side of the game, including team line-ups, the boxscore, and team statistics. Users can also view their "player tracker", which will alert the user when a player in their chosen player list is active in a game.
According to MLB.com, in 2008: "...all live games will be blacked out in the United States (including the territories of Guam and the U.S. Virgin Islands) and Canada."
MLB.com can check a viewer's origin by using an e-mail address's domain during registration, by using credit card billing information, or by IP address. The intricate blackout rules of Major League Baseball coupled with the inaccuracy of ISP-based targeting can leave a fan unable to watch a game on MLB.com.
MLB Gameday Audio does not have blackout restrictions.

Based on BBB files, this business has an unsatisfactory record with the Bureau, because there is a pattern of complaints, and the business has not corrected the underlying reason for the complaints.
