The document discusses various theories about the impact of advertising on consumers, including the hypodermic needle theory, uses and gratifications theory, and passive and active consumption theories. The hypodermic needle theory suggests that advertising can directly influence consumers by "injecting" them with messages designed to trigger a specific reaction. However, uses and gratifications theory and passive/active consumption theories recognize that consumers make conscious choices about what media they consume and how they interpret messages based on their individual interests and social contexts. The document also analyzes advertisements by Lucozade and Coca-Cola in light of these theories.
