Wasnt around like that in the 80's being that I was just being born, but Clearly the presence of LL Cool J, and Run DMC shows that Hip Hop had already hit the mainstream, these wasnt just some regular ass acts; these were the 1st true superstars of hip hop on that level
there was also a brief period were black militancy was becoming mainstream off the strength of Public Enemy and a few other, That shifted the energy of hip hop from 'let's talk about these sucka MCs' type shyt to some revolutionary type shyt
NWA created a whole new aura around hip hop that scared, yet intrigued white america. even if it wasnt for them
NWA was definitely a catalyst for hip hop as we know it today complete with all the familiar trappings and aestethics. The word of mouth shyt gave them this crazy ass mystique like they were practically straight off the prison bus; this dangerous thing that needed to be censored and banned out of fear that it may corrupt their children.
But it was the transition from NWA and ruthless to Death Row that truly shot hip hop to the absolute apex of pop culture indefinitely. Between Snoop, Dre, and all the fukkery surrounding Death Row, IT was a perfect storm that shifted the paradigm in hip hop on the mainstream level.
Everything in hip hop that followed immediately afterwards benefitted from early DeathRow's foot print on pop culture. So many different interpetations of street music or gangster rap was born out of that shyt because the world all saw how lucrative it was....
After Pac and Biggie passed, Hip hop was gradually building towards another boom period in hip hop starting in 97 until around 2003/04, Migh even be the biggest boom period in Hip Hop history, nikkas was going platinum left and right; East, West and Down South; Speaking of which, No Limit and Cash Money had a HUGE, HUGE, influence on the mainstream appeal of hiphop even though certain nikkas from certain parts of the US like to write that shyt out of the history books. Judge it all you want, But those labels killing shyt the way that they did was the precursor the the 10+ years of the south Dominating mainstream hip hop, whose influence stills continues to this day even if the artist themselves arent from the south.
and it was starting to cannibalize R&B after a while too, that's how big hiphop became in the 2000's
