A. One way in which expressions such as these diffuse is through movies and television. The use of these terms in movies and TV shows influences many people to use them and share them with friends and family. Another way that terms like these diffuse around the world is through social media platforms. In this day and age, social media platforms such as Facebook, Instagram, and Twitter can spread an expression or trend with unbelievable speed. In fact, the primary reason the term “selfie” diffused was because of people posting “selfies” on their social media.
B. Relocation diffusion is when one migrates and takes an expression, idea, or piece of their culture from their place of origin to their new destination. This can result in the spread of popular culture. For example, if an important or famous person were to visit a new place and use a term like “groovy”, it is highly likely that the people there who idolize or are influenced by that person will use that term. Contagious diffusion can result in the diffusion of popular terms as well. Contagious diffusion is the form of diffusion when something diffuses from one person to the next much like a contagious disease. This is especially prevalent in social media and the Internet. When a trend “goes viral” and is shared across the world, it is shared from one person to the next. Hierarchical diffusion can play a large role in the diffusion of popular culture when a person of high importance or influence uses an expression or creates a trend and his/her “followers” start using that expression or following that trend.
C. In some cases, countries may prevent certain expressions or forms of popular culture from diffusing. For example, in China, the government censors certain parts of the internet. This could create barrier in the diffusion a expression. Another barrier that could prevent the diffusion of certain terms is age. Many times, elderly people are less accepting of new trends or phrase, and they prefer to stick to their own ways of speaking and carrying out their life. When a trend forms amongst a younger generation, older people may not want to accept it, and this age gap could be a barrier to diffusion.
