In 2001, they won the World Series over the three-time defending champion New York Yankees, becoming the fastest expansion team in major league history to win the World Series and the first and only men's major professional sports team in the State of Arizona to win a championship.

[9] The Diamondbacks' first major league game was played against the Colorado Rockies on March 31, 1998, at Bank One Ballpark.

[11] Their logo was an italicized block letter "A" with a diamond pattern, with the crossbar represented by a snake's tongue.

The primary sleeved uniform, worn from 1998 to 2000, featured the full team name ("Diamond" and "Backs" stacked together) in front and chest numbers.

The first version featured "Arizona" in purple with white and teal trim along with black drop shadows, with chest numbers added.

The alternate home purple uniform featured "Arizona" in teal with white and copper trim and black drop shadows.

The franchise unveiled new uniforms and colors of Sedona red, Sonoran sand and black on November 8, 2006.

One design has the alternate "A" logo on the right chest, while the other has "Arizona" written in red with black and sand trim.

Before the 2016 season, the Diamondbacks reincorporated teal into its color scheme while keeping Sedona Red, Sonoran Sand and black.

Arizona also kept the throwback pinstriped sleeveless uniforms from their 2001 championship season for use during Thursday home games.

The team also reverted to a standard grey uniform after wearing a darker shade on the previous set.

They would also wear two black uniforms: one with the primary "A" logo on the left chest and the other with "Los D-Backs" trimmed in teal.

[18] Coming off their second World Series appearance in 2023, the Diamondbacks unveiled refreshed uniform designs starting in 2024.

The home uniform is now a cream base with black piping, featuring the "A" logo on the left chest.

Games air on the following cable providers and networks:[21][22] The primary television play-by-play voice for the team's first nine seasons of play was Thom Brennaman, who also broadcast baseball and college football games nationally for Fox Television.

In October 2006, Brennaman left the Diamondbacks to call games with his father for the Reds beginning in 2007, signing a four-year deal.

The Diamondbacks announced in July 2007[24] that for the 2008 season, all regionally broadcast Diamondbacks TV games would be shown exclusively on Fox Sports Arizona (now Bally Sports Arizona) and a few could possibly be shown on the national MLB on Fox telecasts.

From 2009 to 2012, Grace and Sutton were tagged as the main broadcasters of the Diamondbacks with pre-game and postgame shows on Fox Sports Arizona, being hosted by Joe Borowski.

[25] On August 24, the team announced that Grace had requested an indefinite leave of absence after being arrested for his second DUI in less than two years.

[28] On October 18, 2012, the team announced that Bob Brenly would return as a broadcaster to replace Grace and that he would be joined by then-ESPN personality Steve Berthiaume.

Greg Schulte was the regular radio play-by-play voice, a 25-year veteran of sports radio in the Phoenix market, also well known for his previous work on Phoenix Suns, Arizona Cardinals and Arizona State University (ASU) broadcasts.

[32] Mike Ferrin served in the same role for six years before parting ways with the team, and he was replaced by Chris Garagiola in December 2021.

[33] The flagship Spanish language radio station is KHOV-FM 105.1 with Oscar Soria, Rodrigo López, and Richard Saenz.

[31] Games were televised in Spanish on KPHE-LP—with Oscar Soria and Jerry Romo as the announcers, but this arrangement ended prior to the 2009 season due to the team switching fully to Fox Sports Arizona and the lack of carriage of KPHE-LP on the Cox cable system.

After eliminating the Diamondbacks and clinching the division on September 19, 2013, multiple Dodgers players celebrated the win by jumping into the pool at Chase Field.
