La Sexta, a privately owned Spanish free-to-air television channel operating under Atresmedia, is headquartered in Spain. Founded in 2001, the company employs approximately 60 individuals and reported $17.1M in revenue as of 2023, functioning as a tier 2 media tech buyer. Its operations encompass broadcast television and radio, with its origins tracing back to its founding as Beca TV in 2001, initially broadcasting on April 1, 2001. Following a shutdown due to debt in 2003, it was replaced by a new channel under the name La Sexta in 2005, which commenced test transmissions on November 25, 2005, and officially began broadcasting on March 27, 2006.
On January 26, 2026, Cuatro's program "Horizon," presented by Iker Jiménez, entered the prime-time access slot, achieving a 7.6% average screen share and 989,000 average viewers. This programming shift followed audience reports on January 4, indicating La Sexta surpassed Telecinco in viewership during coverage of the Venezuelan attack and subsequent capture of Maduro, though TVE dominated overall. Earlier, on January 2, reports confirmed that Cuatro had surpassed La Sexta's audiences in December 2025, marking a historic moment for the Mediaset network as it had not outperformed La Sexta since June 2021, ending a 53-month streak. Previously, on December 18, 2025, La Sexta altered its Sunday night schedule to broadcast a special "Al rojo vivo" with Antonio García Ferreras and Ana Pastor, providing extensive coverage of the Extremadura elections.
