Hungarian Spectrum was published daily, seven days a week, starting June 27, 2007. It has been permanently archived in the
Library of Congress as of 2013 where it remains available online, as well as in the
Blinken Open Society Archives. Balogh, who specialized in interwar Hungarian history, researched and wrote most of the articles. Based on primary sources in Hungarian, German and English, the articles analyzed current developments in Hungary for the nonspecialist reader from a historian's perspective. The blog also occasionally included articles written by guest scholars such as
Kim Lane Scheppele,
Johanna Laakso, Charles Gati and
Randolph L. Braham.
Hungarian Spectrum was supported by voluntary donations from its readers. Businessman
George Soros, winner of the
Ridenhour Prize for Courage in April 2019, donated his prize money to
Hungarian Spectrum, describing it as a site that "renders an important service by exposing to the world what Prime Minister Orban is telling his own people." Following the death of Balogh,
Hungarian Spectrum ceased publications. ==Political orientation==
