The Information Age, also commonly known as the Computer Age or Information Era, is an idea that the current age will be characterized by the ability of individuals to transfer information freely, and to have instant access to knowledge that would have been difficult or impossible to find previously. The idea is linked to the concept of a Digital Age or Digital Revolution, and carries the ramifications of a shift from traditional industry that the Industrial Revolution brought through industrialization, to an economy based on the manipulation of information. Commonly seen as an outflow from the Space Age, capitalizing on the computer microminiaturization advances of that effort, with a fuzzy transition spanning from the advent of the personal computer in the late 1970s to the internet reaching a critical mass in the early 1990s, and the adaption of such technology by the public in the two decades after 1990. Since the invention of social media in the 2000s, the Information Age has evolved into the Attention Age according to some publications.
