This thesis is based on the definition and investigation of the sampling phenomenon in the music and film industry. How sampling affects these industries, how it has developed and what it encompasses. The paper examines the cultural significance of music in today's world, an overview of the history of hip-hop music and the birth of sampling through hip-hop. It also explores the sampling techniques used today and provides an overview of the sampling techniques used throughout history. Sampling is also present in the film industry, which is explored through an overview of music in silent films and further in sound films with a greater focus on popular music in films. Examples of some of the most famous films with impressive music will be used to show how music is used in film and why it is important for a better viewer experience. It also defines what temp tapes are and how they are used in modern films. The thesis also addresses the complexity of the sampling concept and shows why the use of sampling is not as easy and free as it may seem. The definition of copyright provides a better insight into the legal issues musicians face when sampling. It also examines how copyright affects musicians' further work with sampling. This thesis will attempt to examine in more detail the sampling technique, which is ubiquitous and highly influential in the development of music and film in the postmodern era, but is still very much neglected and underappreciated.
