when did bluetooth come out

Bluetooth technology first sauntered onto the scene in 1999, promising short-range wireless communication without the mess of wires. Originally developed by Ericsson back in the late 1990s, it aimed to replace RS-232 data cables. Today, it's a ubiquitous feature in everything from phones to cars, making our lives slightly less tangled.
