Can you tell me how and when did oxycodone become popular?

Oxycodone: Oxycodone was discovered in 1916 but it didn't get popular until the mid 1990's because of he manufacture's aggressive marketing to docs. It was initially quite cheap and so the illicit drug trade could get large quantities and then sell it on the street. Its also fairly long acting so high lasts longer. Its illicit use has killed tens of thousands of Americans silently.
