It was formed in 1995 as a 50-50 joint venture between the Greek Marinopoulos Group and the French Carrefour Group, but, in 2012, Carrefour decided to withdraw from the joint venture due to the Greek financial crisis.

[3] It was the biggest retail chain in Greece in terms of both turnover and number of stores.

Carrefour Marinopoulos stores are divided into three formats, differentiated by size and the range of products sold.
