Was RocknROLL Ever referred to as Rock Culture

Or is this just specific to rap as in "hiphop" culture? If it starts to wane in the future will pbs start a Preserve our hiphop culture telethon complete with tote bags?

50 years from know a blue haired granny will be manning the phone of said telethon,she will ask for a donation to keep her youth of being a jigga ho alive for future generations.
