How has the way we consume knowledge shifted due to the evolution of book marketing in America? We live in a digital world with thousands of social media outlets. While in the 1950s, most people would turn towards books as their primary source of entertainment; we now turn to icons on our phones. As seen in classics such as Great Expectations, Serialization has shifted to digital renditions such as ‘Webtoon’ Comics. Publishing companies know that it is vital to adapt to this rapidly changing world and have, in turn, shifted the way books are marketed to coincide with the digital. I examine how this has affected the human population and the individual. Do we consume knowledge differently now? As posters shift to short blurbs on TikTok, how do we look at the world change? How does our brain plasticity change from physical books to digital touchscreens? I am writing a research paper on this subject focusing on three spheres: the biological sphere, the psychological sphere, and the marketing sphere. Through surveys conducted on teenagers, authors, and Barnes and Nobles employees and quantitative statistics from Amazon and TikTok, I further explore the significance of this phenomenon.
