Initially a A&M Records sublabel, I.R.S. moved distribution to MCA Records in 1985, and to Enigma Records (3) in 1990.
Some I.R.S. releases were issued for the UK and continental Europe through Copeland's label Illegal Records (2). Copeland also established local I.R.S. offices in conjunction with his Illegal divisions in those countries.
Please add to the release/submission notes anything that would help clarify the country and label situation, such as any fine print regarding copyright and marketing/manufacturing/distribution etc.
I.R.S. was closed down in 1996, and in 1997 Copeland formed a new label, Ark 21 Records.
The EMI Group revived the I.R.S. label with a new roster in 2011.
