The laSexta programme, produced in collaboration with Secuoya, achieved its best figures in six years in 2025: a 5.9% share, an average of 612,000 viewers, and 1.9 million unique viewers per broadcast
‘Equipo de Investigación’, laSexta’s programme hosted by Glòria Serra, celebrates 15 years on air, firmly established as one of Spain’s leading references in investigative television journalism. Produced by Atresmedia in collaboration with Secuoya (CBMedia), the programme has maintained a distinctive and consistent identity, committed to field reporting, cross-checking sources, and building solid narratives that help audiences understand the country’s social, political, and economic reality.
A record-setting 2025 for the programme
In 2025, ‘Equipo de Investigación’ posted its best results in the last six years, with an average 5.9% audience share, 612,000 viewers, and 1.9 million unique viewers per broadcast—figures that underscore its strength as a long-running format and its leadership within the investigative TV genre.
Fifteen years after its debut, the programme remains fully capable of investigating, contextualising, and explaining the issues shaping the public agenda. Glòria Serra continues to lead each report—one of the key figures in investigative television journalism—whose voice and editorial judgement define the programme’s tone.
A distinctive language and a recognisable methodology
The professional team behind ‘Equipo de Investigación’ has developed its own narrative, visual, and editorial language, easily identifiable to audiences and also influential in the digital space. Its methodology is grounded in on-the-ground reporting, direct access to protagonists, locations and documentation, and a research process that clearly defines what is being investigated and how.
Over these fifteen years, the programme has aired 555 reports, interviewed nearly 16,000 people, and built an archive of more than 25,000 hours of footage—a unique audiovisual legacy documenting how Spain has evolved through investigative journalism. This is made possible by a team of 50 professionals across direction, editorial, production, editing, realisation, and camera crews.
Topics, impact and international reach
The programme’s wide thematic scope ranges from crime, corruption, scams, drug trafficking and consumer issues to major social phenomena, investigative exposés and character profiles. Over its run, it has delivered key investigations on 23F, the Franco family’s assets, the Urdangarín case, El Pequeño Nicolás, as well as reports on Marta del Castillo, La Veneno, the DANA, and major scandals linked to housing and fraud.
The format also enjoys significant international reach, especially in Latin America, and is available outside Spain via Antena 3 Internacional and the international version of atresplayer, confirming its ability to tackle stories with global relevance.
An anniversary at one of its strongest audience moments
‘Equipo de Investigación’ closed 2025 as a stable prime-time format. Throughout the year, close to 20 million people watched the programme hosted by Glòria Serra at some point.
Its performance is supported by a loyal and stable audience with a high viewing time. It stands out particularly in the commercial target (7.6%) and among viewers aged 35–44, where it exceeds a 10% share.
The year’s most-watched episode was “Daniel Esteve y el negocio del miedo” (January 31), with 820,000 viewers and a 7.3% share. The report with the highest share was “Historia de la DANA: Las horas ausentes” (October 28), with a 7.5% share and 623,000 average viewers.
Across its fifteen-year run overall, the programme averages a 7% share, close to one million viewers on average, 3.2 million unique viewers per broadcast, and a total reach of 43 million people.
Time-shifted viewing has also shown sustained growth, averaging 50,000 viewers per broadcast and reaching 1.2 million annually, confirming the strength of the content beyond linear broadcast.
A format that builds community and expands
‘Equipo de Investigación’ goes beyond the screen and has become a brand with a strong digital community. In 2025 it was laSexta’s second most-consumed format in digital, with 6 million plays, more than 3 million social interactions, and 166 million content views (excluding X), building a community close to one million followers, known as equipers.
“La luz del mundo: faith, power and control”
To coincide with its 15th anniversary, laSexta will air, on Friday at 10:30 pm, report number 555, titled “La Luz del Mundo: faith, power and control”, an investigation that encapsulates the programme’s DNA.
The report analyses the expansion in Spain of La Luz del Mundo, a religious organisation whose leader is serving a prison sentence in the United States for the sexual abuse of minors. The investigation focuses on its growth in Spain, with dozens of temples across the country, and begins in Madrid during the celebration of the Santa Cena, marked by secrecy and internal control.
Fifteen years after its debut, ‘Equipo de Investigación’ continues to prove that investigative journalism on television remains necessary, relevant and capable of generating social impact.
