SlideShare is a website launched in 2006 that allows users to upload and share presentations. It has grown to host over 18 million slides, videos, and documents that are accessible to both businesses and individuals. The story is told of a teacher named Donald who is unhappy because he forgot to create a powerpoint for his class the next day. However, with SlideShare, Donald can now access and download presentations uploaded by other users to solve his problem instead of having to work all night to create one himself. Basic tips are provided on how educators can sign up for SlideShare and have their students share presentations while also exploring content for professional development purposes.
