Mapping, or Alternate Future, is the term for predicting fictional events that will happen in the future. It commonly revolves around speculation of what will happen in the future. However, this term should not be confused with alternate history, or an alternate future caused by alternate history.
The term "Mapping", used as a substituting word for alternate future, is based off of the fanbase of alternative future, alternate history, history, etc. In a certain context, it refers to any mapping video with characterization or personification of countries and their interactions starting with MervueMeringue. It comprised of maps of Europe, which lead to a person, called TheJarJar99, to create the term Mapping. It was later popularized and made official by 99batran whom coined the term for the fanbase called "Mappers". The term had later been officially used by MervueMeringue.
In 2010, Matthew Nicolson, or known as MervueMeringue, created a video showing an alternate future of events fictionally predicted by himself, and making it realistic. Real-world countries were shown in the video, and personification took place in them. The "countries" would fight with each other, creating tensions in the fictional world of Nicolson's mind. Two years later, a person on YouTube called TheJarJar99 made the second video of Mapping, clarifying the term in more detail. The "countries" turned certain colors depending on their actions. For example, they turned any color if they were at "war" with each other, or white when they were speaking. This gathered attention for Mapping, but didn't inspire others to do it. Later that year, however, a person named Brandon, or known as 99batran, was inspired by Nicolson and started to make Mapping videos. 99batran revolutionized Mapping, and made it more popular and widespread than TheJarJar99 or MervueMeringue. More people gained attention to the videos, such as EthanConquistador and HistoryMapper, whom then decided to make Mapping videos of their own. In October 2012, 99batran used the hosting service site Wikia to create TheFutureofEuropes Wiki, an encyclopedia for Mapping and the fanbase of it. This gained attention of TheJarJar99 and EthanConquistador, but not much other early Mappers. The fanbase grew wider and bigger as more people started to be inspired by older Mappers, eventually starting a new breakout of Mapping. In the years 2013 and 2014, a huge number of people started to do Mapping. In middle 2015, though, the fanbase grew to 700 people Mapping. In Mid 2016, it grew to an estimated 1100+.
Various other websites have been doing mapping before the TFOE community, however, they do not do animated mapping most of the time, just one moment in time. These include websites like alternatehistory.com, althistoria.proboards.com, and althistory.wikia.com. Most of these are more focused on the timeline behind the map than the actual map. However, Mapperdonia's kind and definition of mapping differs.
