Kaching originates from The Sims life simulation series created by Maxis and first released in 2000, where the cash register effect plays when a household gains Simoleons from jobs, selling objects or using money cheats. Players heard it hundreds of times while building and furnishing homes, so the sound became deeply tied to virtual wealth. As Sims clips and money memes spread on YouTube and TikTok, editors lifted the effect for real life wins, sales and payday jokes, where viewers recognise it instantly without any explanation needed.
