Banker (“Банкеръ”) is a media outlet that for the last 30 years has consistently covered in detail topics related to the economic and financial life, the problems of the business, as well as the political processes and changes in the state.

The first issue of the Banker newspaper appeared on the Bulgarian market on April 12, 1993. In those turbulent times of sudden changes, filled with difficulties, disappointments, but also with many hopes, it made an impression with the idea of not disappointing, especially the ones who were committed to integrity and were open to the new.

For 28 years the newspaper was printed every Friday in 48 full-color pages. In 2021, the printed edition of Banker was transformed into a digital newspaper (eBanker.bg) and a daily news site (banker.bg).
