It is a Christmas tradition to put up a christmas tree in the living room. In contemporary society is becoming common practice to use an artificial tree as we perceive this to be a better alternative to the real. However, we still refer to this as a 'christmas tree' due to its resemblance despite not being a tree at all - it is a fabrication of one, a copy. The image below references this theory in a more exaggerated form. Several books have been arranged in such a way to resemble a christmas tree yet a real tree could easily have been used - is this perceived to be a better alternative? Despite attempting to replicate the original? This replication of reality becomes the new original.
The over-commercialisation of christmas is often associated with the TV special, A Charlie Brown Christmas (1965). The idea of hyperreality is reinforced within the plot of this programme. The protagonist, Charlie Brown, ignored requests to get a 'big, shiny aluminium tree' and instead purchases a smaller, less aesthetically pleasing 'real' tree. However, in comparison, the replication of the original seemed much more desirable, hence why Aluminium trees became more popular in the 1960's. Artificial trees have soon become the norm in contemporary society as we believe an artificial replication is better than the original.
