Communication has evolved significantly over time due to technological advances. Cavemen communicated through illustrations, while people in the 6th century wrote with feather and ink. The telegraph, telephone, cell phones, internet, and apps like Skype, Twitter, and Snapchat have all allowed for faster and more convenient communication over increasingly greater distances. However, some argue that new communication technologies have hindered deeper human connection by replacing face-to-face interaction with interaction through screens.
