The parliamentary bill was approved in Alþingi on 26 April 1982. After the passing of the ISO law in 1982, the orchestra received provisions on the national budget. The number of players in the ISO had grown and kept growing during this period. The orchestra had 40 salaried players in 1950, 65 in 1986, 72 in 2000 and 95 in 2016. In 1986, the ISO offered season tickets and subscription packages for the first time. The subscription system was based on four types or “series”: Yellow series (large orchestral works, local soloists), Red series (solo concertos, foreign soloists), Green series (accessible music, e.g. Viennese waltzes and operettas) and Blue series (contemporary music and Icelandic works). The system underwent some changes during the next years and in 2016, it is arranged as follows: Red series (with a primary focus on large orchestral works), Yellow series (mostly Classical and early Romantic works), Green series (popular favourites) and Blue series (family concerts). The ISO is active in collaborating with Icelandic schools and regularly holds 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 introduce Maximús Músíkús, a mouse mascot aimed at young children. In family concerts, Barbara and Maximús have been regular guests ever since. In 2009, the ISO's Youth orchestra was established. Each year nearly 100 young students from music schools around Iceland have gathered together under the aegis of the Iceland Symphony to form the Iceland Symphony Youth Orchestra. The Orchestra has performed some of the most demanding pieces in music history such as Symphony no. 5 and Symphony no. 10 by Dimitri Shostakovich, The Planets by Gustav Holst, Symphony no. 5 by Gustav Mahler and most recently The Rite of Spring by Igor Stravinsky. Despite the students' young age and inexperience, the orchestra has been praised many times for its admirable performances and deep interpretations. In 2016, The ISO's Youth Orchestra was awarded the Brightest Hope prize at the Icelandic Music Awards which it had been nominated for before in 2011. The ISO normally holds around 60 concerts each year. Concerts are broadcast live on RÚV's Rás 1 (national radio station).
