The ‘Marketing Mix’ is made up from the collective decisions a company has to make to bring a product to market, and the 4 Ps is one of the best-known ways of visualizing these decisions.
- Product
- Price
- Place
- Promotion

Digital channels are now more prevalent than ever and downloadable content is easily accessible, As such the 4Ps have been extended to the 7Ps to look deeper in to People, Processes and Packaging but the 4Ps have been consistent since the 60s and form a good foundation to build your marketing mix.
