The First Computer Bug Was an Actual Bug - Apparently.
In 1947, a team of engineers working on the Harvard Mark II computer discovered a moth stuck in one of the relays, causing the machine to malfunction. This incident led to the term "bug" being used to describe technical glitches. The team taped the moth to the computer log with the note "First actual case of bug being found" and dated it June 30, 1947. This event marked the beginning of using the term "bug" in computing, a phrase that has since become an integral part of the industry's lexicon.
