use mobile and web-based technologies for communicating and networking between individuals and organizations. Such networking shares, creates, discusses, and proliferates information in both textual and visual form. Social media have dramatically changed how information about wine is disseminated.

Increasingly, wine experts and consumers alike share wine information and opinion via social media channels such as Facebook, Twitter, Instagram, and wine blogs (see information technology).
