I think the study of semiotics and symbols has the potential to be, at times, a very complex study.
Although it took me some time to think of an outer world example of semiotics, I decided to focus on symbols and advertisement. To get a message across, companies that are advertising their product use a range of different media texts to promote their product. However, for it to be successful- there must be a similarity across all of them to make sure that the audience understands what product is being advertised to them. This means that in television and radio, a recognisable “jingle” or catchphrase will be used so that the audience members recall the product that is advertised. Visually, commercials in print and televisions will use the same colours as the company logo, to establish their business and to make sure it is continuously memorable and recognisable to potential consumers.
An direct example would include the McDonald’s franchise. There is a repeated jingle that is placed at the the end of television and radio commercials. Visual advertisements such as print or television always showcase the red and yellow logo, to establish the company to the audience members.
