on the issue and chairman Jónsson was opposed to the shift. The final result, however, was a rearrangement of the orchestra as a subdivision of RÚV. The arrangement was intended as a temporary solution but remained unchanged until 1982 when Alþingi passed a law on the ISO. Collaboration with Þjóðleikhúsið remained virtually unchanged until 1971 when a contract was made between the two institutions, loosening the ISO's players from their former duties as unpaid participants in the theatre's performances. In 1961, the ISO was transferred to its new residence in Háskólabíó, Reykjavík's largest movie theatre. This was the first time that the ISO was able to practice on a permanent basis on the same location as its concerts were held. However, dissatisfaction grew since the acoustics of Háskólabíó were considered unsatisfactory for orchestra concerts. Bohdan Wodiczko, principal conductor, expressed his dislike of Háskólabíó early on and for the next decades, similar views are frequent in interviews with conductors, players and other people connected with the ISO. Háskólabíó remained the orchestra's main venue for fifty years until the opening of Harpa Concert Hall in 2011. During the 1960s and 1970s, the ISO gradually grew and developed. No formal regulations existed on the orchestra's management and its relationship with sponsors was more or less random. In 1976, Vilhjálmur Hjálmarsson, minister of culture, appointed a committee to write a parliamentary bill for the ISO. The committee wrote a draft which was rearranged by a new committee, appointed in 1978. The proposals underlined the importance of the ISO's independence towards RÚV and Þjóðleikhúsið – the orchestra should be able to stand on its own and not only serve as a satellite of the other two institutions. The parliamentary bill was approved in Alþingi on 26 April 1982. Institutionalization (1982–2022) After the passing of the ISO law in 1982, the orchestra received provisions on the national budget. The number of players in the ISO subsequently grew, with 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
