Explanation: A form of brand or advertising campaign that involves a well known person using their fame to help promote a product or service. Manufacturers of perfumes and clothing are some of the most common business users of classic celebrity endorsement techniques, such as television ads and launch event appearances, in the marketing of their products.
Celebrity endorsement refers to a form of advertising in which companies, brands, or non-profit organizations use celebrities to promote a product, service or transmit any message wanted. As the person used is a well-known, respected member of society, the company or brand expect he/she enhances the cfedibility of the product or business. It is important to mention that the right celebrity must be chosen in order to have a succesful advertising campaign. That means that the celebrity must fit with the characteristisc of the product. For example, if you want to advertise some running shoes, you need to choose someone that is known for being fast, like Usain Bolt. In this way an association between the characteristics of the celebrity and the product is done.
The meaning of the word 'inert' is 'not moving'. In the excerpt, it is described that the machines were not moving, as if they were dead. The word 'inactive' has the same meaning - it stands for something that is not operating, moving or is out of function. This is why we could replace 'inert' with 'inactive' in this example.
