Warner Special Products was formed as a division of Warner Brothers Records in the early 1970s. At the time, most major record labels had Special Products (or "Special Markets") divisions to custom press albums for customers who wanted advertising giveaways, special albums to sell, etc. Warner Special Products did not try to crack the market for custom advertising, but rather began pressing records for sales on radio and especially television.

Releases will often list both a Warner Special Products catalog number as well as a catalog number of the marketing label.
