(c) Competitive advertising – claims that a product is better than rival brands, to win market share from close substitutes.
(d) Mass (collective/generic) advertising – joint advertising by producers of the same kind of product to increase demand for the product generally, sharing the cost (e.g. 'drink more milk').
