Theo Filippopoulos got his Master degree on Civil Engineering from the National Technical University of Athens in 1989. He started his publishing career at the age of 27, when he took over the Greek financial monthly magazine “Kefalaio” (“Capital”). In 1993 he co-founded “Capital Trade Shows”, a company that organized the annual “Executive Cars” show, as well as the “1st International Car Show” in Greece. In 1994 he founded Attica Publications SA and acquired the rights to publish in Greece the monthly women’s magazine Madame Figaro which signaled the beginning of a very successful publishing course. The big success of Madame Figaro made Playboy Enterprises confide to Theo Filippopoulos their title “Playboy”, which soon became the leading men’s magazine in Greece. On September 1999, after a sequence of business successes, the company, under the guidance of Theo Filippopoulos, was listed on the Athens Stock Exchange. His business acumen soon led to strategic alliances which brought the company, which acquired the rights for more international titles, such as Harper’s Bazaar and Shape, and for Greek popular titles such as Tiletheatis and Tilerama,  to the top of the Greek media market. 

During the years that followed, Attica Publications Group expanded its activities and developed a strong presence in the northern European media scene through strategic joint ventures in Hungary and in Romania. During the period 2001-2008 Attica also founded subsidiaries in Bulgaria and Serbia, acquired a 50% stake of “Prooptiki” - the leading DVD and theatrical distribution company of the country, as well as three highly popular radio stations (Athens Radio Dee Jay, Rock Fm and Lampsi). Between 2007 – 2014 Τheo Filippopoulos served as the elected chairman of MPG (Magazine Publishers of Greece Association) for three consecutive terms.

Theo Filippopoulos is today the President of Attica Publications Group, a media group with several subsidiaries and affiliated companies in Greece, Serbia and Bulgaria, as well as the President of Capital.gr which publishes the weekly financial newspaper Kefalaio and runs Capital.gr, the leading financial website in Greece.
