Monster / energy drinks Rockstar?
Who Monster / Rockstar Energy drinks target as a consumer? (I heard 18-30 years but always thought it was teenagers are objective) How to appeal to young adults rather than teenagers? What is your marketing strategy?
I do not think they are really aimed at any particular age group, only for people who like drinks with caffeine. I'm surprised how many adults are drinking because children and adolescents. I would say that appeal to young adults because young adults tend to work and not enough sleep, so they feel they need stimulants such as caffeine.
