History

The charts were first broadcast on RTÉ on 1 October 1962. Before this charts had been printed in the Evening Herald newspaper, but it is debated as to whether they are official or not. Up until 1972 the Irish Chart was based on telephone sales received from record retailers based on over the counter sales to the public. The compilers of the chart changed several times and in January 1972 the chart changed to one based on sales from manufacturers to retailers. From October 1975 to February 1977 the chart was compiled from votes from readers in the Evening Herald newspaper. There was a separate Irish and International artists chart for a time during this period. From 1977 the chart once again became based on sales from retailers to the public but during the early 1980s this again changed and was once more based on sales from manufacturers to retailers. RTÉ 2fm broadcasts the top 30 of the chart every Friday night from 8pm to 10pm.


In 1992, the singles chart became based on consumer sales after IFPI and the Irish Recorded Music Association (IRMA) granted a contract to Gallup, a market research company. Gallup installed Epson PX-4 devices in sixty record stores to collect singles sales data. In 1996, Chart-Track was formed as a result of a management buy-out from Gallup. Also in 1996, with the development of technology, EPOS systems were installed in multiple music retail stores. The EPOS systems allowed for the collection of more accurate sales information. Chart-Track collects data daily from major record stores such as HMV and Tower Records, as well as over forty Independent retailers. In total, data from over four-hundred and ninety stores are collected each week. The singles chart is compiled over seven days and released every Friday at noon by the IRMA, while Midweek Charts are produced daily, but only released to IRMA members.


It was announced that from 1 July 2006, downloads would be counted in the charts. They would also feature in their own chart in addition to being counted for the overall chart. Data was initially collected from iTunes, Vodafone, eircom, Sony Connect, Wippit and Bleep.com.^[2] Although IRMA estimated the size of the download market to amount to only 14% of the total market in 2006, this has increased in more recent years.


In 2014, the Irish charts first included music streaming data and in 2018, music video streaming data was included for the first time.^[3]
