Cross Promotion and Synergy

Synergy - In advertising when a brand or product has a consistent message, colour scheme, advert story and actors across many platforms we call this synergy. For example, if you were to look up the latest perfume you would see that the webiste, poster and TV advert will all look identical and feature the same things. This consistency is know as synergy.

Cross Promotion - This is when a product teams up with another product and they help to advertise each other. 

Find some examples of this but for the music industry and music artists.
