In this day and age advertising is big business. It lays a lot of effort into effectively introducing the public about a product or service. Advertisements are introduced through a variety of means. Companies can choose through the print media, television, radio or even huge lit-up billboards that have been put up around our cities and which approve that we buy this type of ice-cream or that type of trainer. Advertising companies use a number of techniques to attract our attention, including stunning photograghy, eye-catching graphics, jinggles or clever comments. What is more, companies may employ famous people like film stars to advise their products.
However, many governments have introduced rules and regulations that advertisers must follow. These codes of conducts ensure that advertisers don't make exggerated claims or offend groups of people. In some countries, advertisements can be displayed only in specific areas. Likewise, some countries do not approve of the advertising of certain products, like tobacco, so they don't allow such advertising at all
