Conventions of dairy advertising

I have been looking into the conventions of dairy advertising as a whole, as it is difficult to gain an understanding of the conventions of advertising milk, as there are only a few milk brands, and very few milk adverts besides the cravendale ads. I looked at a multitude of adverts for yoghurt, cheese and butter and have come up with what seem to be the conventions and codes

Obvious conventions -
- images of country side and greenery, signifying a natural, seemingly organic product
- free range cows, whether this is how their cows are treated or not, this gives the product a good brand image
- references to "british heritage"
- lots of branding, featuring the logo and products colours where possible, as much of the selling point of these product is their branding - no actual difference.
- a clear display of the product in use, pouring milk or spreading butter, often a close up
- upbeat, feel-good music, helps the consumers bond with the product.
