Educational technology has evolved greatly over time. Some key developments include the printing press in 1453, the typewriter in 1872, the VCR in the 1960s, CD-ROMs becoming common in computers in the 1980s, and the World Wide Web beginning in 1989. More recent innovations include iMacs including built-in cameras for recording lectures in the early 2000s and the increased use of wireless devices and the internet for learning by 2005. Interactive whiteboards have also enhanced classroom experiences by allowing anything on a computer screen to be projected large and interacted with.
