Marketing is the creation, communication and distribution of ideas in the hopes that customers will purchase the products or services involved. In the past, marketing was a creative process that was expensive and time-consuming. With the development of technology, marketing has become more accessible and efficient. In particular, guerrilla marketing is a short history of how marketing has changed over time. Marketing has been an important part of our lives for many years. In the 1940s and 1950s, companies used marketing to identify and reach new customers. For example, advertisers would send out 'samples' to potential customers to promote their products. At this point, advertising was referred to as 'mass marketing.' During this period, companies used direct mail and drip campaigns to target their desired audiences. Many companies also set up sales offices in major cities to target regional or city-wide markets. This era saw tremendous growth in sales and media consumption. In the 1960s, economist Joseph Schumpeter introduced the concept of 'graphic marketing.' He referred to the use of advertising to promote products. Graphic designers used new printing methods to create compelling advertisements that have helped shape society. The most well-known advertisement from this period is the 'IKEA catalogue.' Today, social media makes it even easier for companies to efficiently advertise products through social channels like Facebook and Twitter. advertising agencies have also introduced digital methods for targeting consumers with advertisements. One of the most famous advertising campaigns in history is probably not what you think it is. In 1963, David Ogilvy launched his 'I'd Like to Suggest…' ad campaign for British Petroleum (BP). The ads featured a gas pump with a sign hanging off it that read: 'Negative cash flow since 1962.' The pictures suggested problems BP had faced over the years but were humorous enough that people didn't take them too seriously. In fact, this was one of the first advertising campaigns to successfully address serious issues with humor in order to educate consumers. Since then, numerous other advertising campaigns have followed similar tactics - using lighthearted humor to address serious issues and garner attention for corporations or brands. Marketing has become much easier due to technological advancements in the field. Companies can reach new customers easily by using social channels like Facebook and Twitter or digital marketing tools like email campaigns or digital ads. Thanks to Ogilvy's bat tactic, marketers are no longer stuck spending their lives swatting away competing flyers from airports- they've got Guerrilla Marketing!
