What is a likely effect of television advertising on both children and adults?

Concept: Mass media is an agency of socialisation — alongside the family, the school and the peer group, it transmits attitudes, aspirations and consumption norms to whoever is exposed to it. Television advertising is persuasive communication that works through repeated exposure, brand recall and aspirational imagery. Those mechanisms act on the viewer, not on a particular age; anyone who watches is inside the audience the message is designed to move.

Application: The stem asks for an effect that is common to two audiences at once, so the effect has to be one that the mechanism above can produce in each of them:

• Young viewers form brand recognition and brand liking early, and the resulting requests to parents feed into what the household actually buys.

• Adult viewers carry the same recall and imagery into the point of purchase, where it guides which brand is chosen from the shelf.

The one effect that operates in both audiences is therefore the shaping of consumer preferences across ages — advertising moves what people want to buy, in every age group that watches.

Cross-check against the other claims:

• A blanket denial that advertising touches family decision-making cannot stand, because advertising-driven requests from children are a documented input into household purchases.

• An automatic gain in critical thinking does not follow from exposure either: analysing an advertisement's claims is media literacy, a skill developed through teaching and guided practice, while the advertisement itself is built to persuade rather than to train reasoning.

• Confining the effect to children ignores that adults are the demographic most campaigns are planned and bought against, and adults are the ones who make the payment.

Result: Television advertising shapes consumer preferences across ages.
