Slideshare began in the 1600s as a way to present a series of images and videos on a screen, with each slide displayed for a few seconds before changing. It has since evolved into a global platform used by businesses for lead generation and content marketing. Slideshare allows users to upload presentations and share them publicly, making it a powerful tool for companies to clarify information verbally and engage their target audiences. Many well-organized top brands now use Slideshare to supplement oral presentations with visual content.
