A media is a vendor that sells advertising space to organizations (e.g. NY Times) in order to promote their brands, products, services, or events.
Each media supports differents formats of advertising space. (e.g. Full Page 4 colours, Half Page, etc.)
Defining formats up-front is a good way to store your negotiated costs, to standardize naming convention across your team and to accelerate your data entry when planning new media insertions.
A media also has contacts with which you interact to get information, book a media insertion, or deliver the creative files.
You’ll be able to quickly access the contact of your media representative to get more information or book media insertions.
Defining contacts up-font is a good way to share your team rolodex.
