A month after having decreed the reform, the pope with a brief of 3 April 1582 granted to Antonio Lilio, the brother of Luigi Lilio, the exclusive right to publish the calendar for a period of ten years. The Lunario Novo secondo la nuova riforma printed by Vincenzo Accolti, one of the first calendars printed in Rome after the reform, notes at the bottom that it was signed with papal authorization and by Lilio (Con licentia delli Superiori... et permissu Ant(onii) Lilij). The papal brief was later revoked, on 20 September 1582, because Antonio Lilio proved unable to keep up with the demand for copies.

During the initial punk era, a variety of entrepreneurs interested in local punk-influenced music scenes began founding independent record labels, including Rough Trade (founded by record shop owner Geoff Travis) and Factory (founded by Manchester-based television personality Tony Wilson). By 1977, groups began pointedly pursuing methods of releasing music independently , an idea disseminated in particular by the Buzzcocks' release of their Spiral Scratch EP on their own label as well as the self-released 1977 singles of Desperate Bicycles. These DIY imperatives would help form the production and distribution infrastructure of post-punk and the indie music scene that later blossomed in the mid-1980s.
When did some groups start looking for methods to release their music themselves?
1977
