Radyo organized the two Istanbul Musical Festivals. Ten thousand people attended each radio festival; the programs featured an eclectic range of music and 125 activities, including activities for children, international panels, world-premiere performances and dance workshops. Açık Radyo co-sponsored two photography exhibitions: "1968 Through the Lens of Magnum" in 1968 and "Portraits of the 20th Century" in 2000. Each exhibition drew an audience of about 8,000. In 2006, Açık Radyo organized a fundraiser entitled "NaturMort" ("Still Life") to draw attention to global climate change. Six art galleries and 83 artists contributed, donating their proceeds to the station. Conferences and panels Açık Radyo organizes five conferences annually. Over 50 conferences have been held at universities and cultural centers, including panels by Açık Radyo editors and programmers on such topics as broadcasting, independent media, freedom of the press, global climate change, globalization and the history of music. Open-space project In fall 2005, a group of students from İstanbul Bilgi University created a programing contest enabling young people to express themselves through alternative media. This was Açık Radyo's first programming contest for university students (“Change the world, even if it’s for an hour a week”), followed by a second contest (entitled “Let’s Play!”) the following year. Sixty-four young people from eighteen universities participated with forty-seven projects. Winning projects were aired on Açık Radyo for six months. Listener-supported projects An opinion poll conducted by AC Nielsen in 2000 showed that Açik Radyo's "core listeners" (those who listen every day) numbered around 45,000; those who listened every other day, 80,000; once a week, 120,000; the number of people who listened at least once during the last three months is around 200,000. According to polls conducted by the Istanbul Foundation of Culture and Arts (IKSV) in 2001 and 2003, among music listeners and film-goers at the International Festivals of Classical Music, Jazz, and the Istanbul International Film Festival Açik Radyo was chosen as the most popular radio station. In early March 2004 a fundraising project, "Açik Radyo is seeking its listeners", was begun to augment the efforts of the 92 founders and 650 volunteer presenters with contributions from listeners to attain a level of "sustainable independence." With the addition of funds raised from a few thousand "listener-sponsors" to income from advertisements and sponsorship, Açik Radyo hoped to reach a level of permanent financial sustainability. During a year-long campaign, listeners were asked to sponsor one (or more)
