Today, people connect earbuds, phones, laptops, speakers, and even cars without thinking twice. A tap, a beep and devices instantly communicate wirelessly. But before Bluetooth transformed modern technology, tangled cables ruled everyday life. The breakthrough began in 1994 when Jaap Haartsen developed the core technology behind Bluetooth while working at Ericsson. His invention allowed electronic devices to exchange data wirelessly over short distances using radio waves.
At the time, it sounded futuristic. Today, it powers billions of devices worldwide. What started as a technical solution inside a telecommunications company quietly became one of the most important inventions of the digital age.
