Collaborating with Icelandic schools and holding school concerts where students of various ages are invited in groups, during the 2000s, ISO expanded its child targeted marketing and promotion to a considerable extent. In 2007, Barbara the clown (played by Halldóra Geirharðsdóttir) performed as concert announcer for the first time and in 2008, the ISO introduced Maximús Músíkús, a mouse mascot aimed at young children. In family concerts, Barbara and Maximús became regular guests. In 2012, the ISO held its first annual Tectonics Festival at the Harpa Concert Hall, as created by Ilan Volkov, chief conductor. In 2013, the principal guest at the festival was composer Christian Wolff. In July 2014, the ISO had 92 members, of whom around 80% were natives to Iceland. The ISO around 2015 held around 60 concerts annually. Concerts were broadcast live on RÚV's Rás 1 (national radio station). In March 2015, the ISO began collaborating with Icelandic telephone company Síminn, broadcasting videos of chosen concerts.
