The document discusses the growth of digital information from the 1940s to present day. It notes that the amount of digital data created annually is growing exponentially and is expected to increase six-fold every four years. However, only a small percentage of total organizational data is structured in a way that is easily usable by computers, while the majority remains unstructured like documents, photos and videos. Ensuring high quality information through accurate tagging, metadata, and reducing errors is important for effectively managing both structured and unstructured data.
