There is a view that the purpose of advertising is limited to selling unnecessary products. I completely disagree with this view, for advertising does entail [HAVE] other significant uses.
First, advertising makes for [leads to] a dynamic economy. That is, a large number of manufacturers tap into ever-increasing impact of advertising to boost their production. People do abuse such power for profiteering, yet such cases are in a great minority. To illustrate, one can come across to scam ad about hair gel, an exception to millions useful, heathy advertisements of personal essentials. Governmental bodies also look to advertising industry in case for major reforms or extreme scenarios like COVID-19. By promoting online government services or major vaccination, officials protect economy from collapsing. It is therefore unreasonable to scapegoat advertisement industry for few scams, since it mainly serves for the greater good.
Second, business do not opt for advertising with a sole aim selling products. Service advertisement is as popular – if not more – as product ads. A healthy part of developing and developed countries are moving from production-based economy to service-based economy, meaning that market for advertising will gradually lean toward services, not trivial products. A case in point would be Uzbekistan, a developing country, where rarely one can find discounted products on the internet or billboards. Instead, delivery services, online taxis and tutoring sessions usually increase their clientele through such ads. Hence, it is an overstatement to claim that advertising is mainly aimed at products.
To conclude, I am adamant that advertising is not restricted to marketing unimportant products. Rather, it is a marked catalyst behind powerful economy and efficient services for public.
