Introduction
710 ESPN, operating on the 710 kHz AM frequency, is a prominent sports radio station serving the Dallas–Fort Worth metroplex in Texas. The station, whose call sign is KXXV, is owned by iHeartMedia and broadcasts a mix of national programming from ESPN Radio and locally produced sports talk shows. Since its inception, 710 ESPN has played a central role in the sports media landscape of the region, providing coverage of local teams, national sports events, and real‑time analysis for a dedicated listener base.
History and Background
Early Years (1970s–1980s)
The 710 kHz frequency in Dallas originally hosted a variety of formats, including country music and general entertainment. In 1979, the station was assigned the call sign KZLA and operated as a daytime country music broadcaster. The call sign and format would change several times over the next decade, reflecting the competitive nature of the Dallas radio market.
Transition to Sports (1990s)
By the early 1990s, the station had identified sports talk as a niche with growing demand. In 1991, the station adopted the call sign KNSH and shifted its format to sports. It branded itself as “Sports 710,” positioning itself as the primary source for sports commentary in the metroplex. The transition was accompanied by an increase in local programming, including game coverage for the Dallas Cowboys, Dallas Mavericks, and Texas Rangers.
Acquisition by iHeartMedia and ESPN Branding (2000s)
In 2003, Clear Channel Communications (now iHeartMedia) acquired the station as part of a larger expansion into sports radio. The ownership change coincided with the introduction of ESPN Radio programming, a national network offering news, analysis, and live play‑by‑play. The station’s branding was updated to “710 ESPN,” and the call sign was changed to KXXV in 2005. This rebranding aligned the station with ESPN’s national identity, enabling the station to broadcast flagship shows such as “Mike & Mike” and “The Jim Rome Show.”
Recent Developments (2010s–Present)
In the 2010s, 710 ESPN expanded its local footprint by adding a lineup of host‑driven morning and afternoon shows focused on Texas sports.
