Promotion is club advertisements,t.v. advertisements,radio commercials,radio spins,mtv,bet,major magazines,tour with Big star,
reality shows,interviews with major radio stations,mainstream media,budget for star collaborations etc.
Internet is straight but you can't reach certain audiences.
Internet does help but if your big on the internet it doesn't mean shit. (Nerds like weird shit or your a mainstream dickrider) <- You can't reach the streets and the average everyday person that doesn't sit by a laptop all day.
Radio is key but not everybody has access to getting their music played.
Don't be unfair like that just cuz your favorite rappers can't resurface at the same level with every type of promotion you can think of. <-Those acts had their time to shine and people ready to see and hear whats new and not so played out.
