When you flip through the pages of a magazine, pass a billboard on your commute home or scroll through your social media feed there's a good chance you're looking at stock photography, illustrations, video and audio. This type of content is the reason iStock was created. Before the inception of iStock back in 2000, the process of accruing stock images was antiquated. Creatives ordered CDs filled with content they could use to support their projects. Now, iStock allows them to browse through high quality audio files, videos and images that are royalty free. iStock users purchase credits, which can then be redeemed for full use of any content on the site.
