# Brazilian Institute of Public Opinion and Statistics

The Brazilian Institute of Public Opinion and Statistics (IBOPE based on the Portuguese language name, Instituto Brasileiro de Opinião Pública e Estatística) is a brazilian originated global market research company. IBOPE provides data on media consumption and advertising investment across all Latin America.
Established in 1942, the name IBOPE is listed in the Brazilian dictionary as a synonym of audience ratings research.

## History

IBOPE was created in 1942 by the radio broadcaster Auricélio Penteado, owner of Radio Kosmos in São Paulo. In that year, he decided to apply research methodologies he had learned while studying in the United States under George Gallup, the founder of the American Institute of Public Opinion, in order to quantify the size of the audience of his broadcast in Brazil.
When he measured the radio audience in São Paulo, Auricélio proved that Radio Kosmos wasn't among the most listened to stations. Therefore, he would dedicate himself exclusively to research. In 1950, Penteado leaves the presidency of the company in charge to a group of directors.
In 1977, Paulo de Tarso Montenegro became the president of the company. One year later, he invited his children, Carlos Augusto Montenegro and Luís Paulo Montenegro, to join the company. IBOPE carried out the first voting intention polls, anticipating with extreme precision the outcome of electoral contests in the late 1970s.
In the 1990s, IBOPE partners with entrepreneurs in Mexico, Colombia, Venezuela, Ecuador, Peru, Chile and Argentina. From these partnerships, the company begins to supply consolidated data for Latin America cable TV. Currently, in addition to Brazil, the company has developed a leadership position across Latin America and a Global footprint.
In 2014, the IBOPE Media division (measuring media audience and advertising investment) was sold to the Kantar Group, which changed its name to Kantar Ibope Media.
In 2025 [[Kantar Group]] reached an agreement to sell the division to H.I.G. for U$1Billion

## Measurement

IBOPE was the first company worldwide to offer the service of TV audience measurement in real time from São Paulo in 1988.
In every city where the audience is measured, IBOPE choose a group of homes at random to represent the population. With the authorization of the family members, each television is equipped with a device called peoplemeter, which identifies and records which channels are being watched.
The device sends, by cell phone system, the information of all changes made by the viewer channel to a central collection of indices that processes, analyzes and distributes to customers.
The system of television audience measurement in real time is used in Brazil, Chile and Argentina.

## Instability

In 2009, the IBOPE was under suspicion of a possible blackout in its system on 22 November 2009 at 9:40 at night. At that time, the device that measures real-time audience numbers stopped working, and the Institute accused mobile operators that they were responsible for the alleged breakdown in the system. But companies TIM and VIVO denied the Institute of Public Opinion in a statement to Rede Record, which was most harmed by the fact happened. Since then, the television station determined on its department of communication not to disclose their numbers over the station's audience, as they say in their research methodologically.
Even respecting the client's rights, IBOPE disagreed with these critics made, considering it was a momentary problem. The company's research follows the code of self-regulation and ethics of the ESOMAR - The World Association of Research Professionals, and also follows the code of ethics of Associação Brasileira das Empresas de Pesquisa (ABEP - Brazilian Association of Research Companies)
In Argentina, IBOPE is also under suspicion, regarding its research methodology. The government of President Cristina Kirchner plans to launch a state system of measuring television audience in the country (similar to British BARB), in a clear challenge to IBOPE, which now dominates the Argentine Market. According to the government of the country, the work of IBOPE is not checked by anyone.
However, the work of IBOPE in the area of media research is audited by independent firms, hired by a committee formed by the clients of this service. In Argentina, the audit is made by the Cámara de Control de Medición de Audiencia (CCMA - Chamber of Control of Audience Measurement).
