KTSM-TV (channel 9) is a television station in El Paso, Texas, United States, affiliated with NBC and owned by Nexstar Media Group.

KTSM-TV was the second television station in the El Paso TV market, behind KROD-TV (channel 4, now KDBC-TV), which debuted in December 1952.

Wyler built the El Paso Aerial Tramway in the early 1960s to allow his staff to maintain the transmitters at Ranger Peak.

Wyler owned the station until his death in 1990, and donated his controlling stake in Tri-State Broadcasting to the El Paso Community Foundation.

Under Pearson's leadership, KTSM-TV flourished, and became a dominant force in the market, until the stations were sold to Communications Corporation of America in 1998.

On October 19, 2009, Communications Corporation of America entered into a shared services agreement (SSA) with Titan Broadcast Management, owner of CBS affiliate KDBC-TV.

However, the station preempted the CNBC program Mad Money which formerly aired as part of the network's overnight block (although it cleared the rebroadcast of the fourth hour of Today which preceded it nationally).

The NET/PBS shows Sesame Street and Mister Rogers' Neighborhood were also broadcast due to the lack of a full-market public television station in the area at the time.
