In the 1970s and the 1980s, Polish music monthly Non Stop published a year-end list of the best selling albums in Poland. In the mid-1990s, two monthly sales lists were launched and published in music magazines. The first one was a top 50 compiled by ZPAV, based on shipment, not sales, which continues to be published to date. The other was a top 100 called Gorąca Setka, printed monthly in Gazeta Muzyczna. This chart was compiled from actual sale figures as reported by over 130 music shops across Poland and included both albums and singles. From autumn 1994 to September 1997, journalist Artur Orzech presented a top 20 albums list on Radio Bis which was later extended to 25 and 30 positions. This chart was also based on actual sales data obtained from about 150 music shops, including albums as well as singles. The official weekly albums chart, OLiS, was only launched in late 2000, and has since consisted of 50 positions. This chart is strictly based on physical albums sales from selected major retailers and do not include digital sales. ZPAV, however, counts both physical and digital sales towards gold, platinum and diamond certifications, as well as the streamingequivalent. In 2017, weekly and monthly vinyl sales charts were launched to reflect the resurgence of popularity of the vinyl format.
Singles charts
There has been no official singles chart in Poland based on actual sales data. In the 1970s and the 1980s, Polish music monthly Non Stop published selected year-end statistics regarding the singles market. The popularity of individual songs has always been reflected by radio polls and hit lists, compiled from the listeners' votes. Some of the most popular were the charts on Rozgłośnia Harcerska with its top 10 regularly printed in Billboard, and Polish Radio 3's Lista Przebojów Programu Trzeciego. Not many singles were released and the market instead focused on longplays and 4-track extended plays. The single format has been somewhat substituted with cardboard records which were produced on a massive scale and sold in large quantities. Efforts to boost the sales of CD singles in the 1990s were unsuccessful and Polish artists have rarely released singles in physical format. In 2010, ZPAV launched the following lists:
