[2][3] In 1835, he founded the Agence Havas, aware of their growing interest in international affairs, translated foreign newspapers and then sold them to the French national press, local businessmen, and the government.

Recognizing that newspapers were not always accurate and often biased, he explored the concept of having his own correspondents in the field who would supply his agency with information.

In order to reduce overhead and develop the lucrative advertising side of the business, Havas's sons, who had succeeded him in 1852, signed agreements with Reuter and Wolff, giving each news agency an exclusive reporting zone in different parts of Europe.

This arrangement lasted until the 1930s, when the invention of short-wave wireless improved and cut communications costs.

To help Havas extend the scope of its reporting at a time of great international tension, the French government financed up to 47% of its investments.
