We can credit coffee-craving inventors for creating the first webcam. In the early 1990s, computer scientists working at the University of Cambridge grew tired of trekking to the office kitchen for a cup of joe only to find the carafe in need of a refill. The solution? They devised a makeshift digital monitor — a camera that uploaded three pictures per minute of the coffee maker to a shared computer network — to guarantee a fresh pot of coffee was waiting the moment their mugs emptied. By November 1993, the in-house camera footage made its internet debut, and viewers from around the globe tuned in to watch the grainy, real-time recording. The world’s first webcam generated so much excitement that computer enthusiasts even traveled to the U.K. lab to see the setup in real life. In 2003, the coffee pot sold at auction for nearly $5,000.
