Digital media consists of electronic communication brought about by computer and digital technologies, encompassing various formats like social media, blogs, websites, digital video cameras, as well as cellular telephones, cable, and satellite television and radio.
Digital media is interactive, quick, and provides a broad reach, often used for news, information, entertainment, and educational purposes.
