From 1926 through 1955, TCU and Texas Tech frequently played as non-conference opponents.
In 1956, Texas Tech joined the Southwest Conference (SWC), and the teams played annually as conference opponents, except in 1957 (as Texas Tech was not a full member of the SWC until 1960), until the conference's dissolution in 1995.
After the dissolution of the SWC, the teams played a home-and-home series in 2004 and 2006 with the home team winning each time (Texas Tech in 2004, TCU in 2006).
In 2012, TCU joined the Big 12 Conference and the teams renewed their annual rivalry.
Texas Tech leads the series 31–25–3. The series' 3 ties came in 3 straight games in Lubbock in 1979, 1981 and 1983. The series has featured many large margins of victory. Texas Tech's largest victory was by 56 points, in a 63–7 victory on November 9, 1985, in Lubbock, and TCU's largest victory was by 55 points, in a 82–27 victory in Fort Worth on October 25, 2014. The 82 points scored was the most points ever scored against Texas Tech and the most points ever scored against any team in Big 12 history. The Frogs and Raiders have only met twice with both teams ranked in the top 25, in 2006 and 2012. Both games were played in Fort Worth and won by the higher-ranked team (TCU 12–3 in 2006 and Texas Tech in 3OT 56–53 in 2012).
