Walkie talkies were first invented in 1938 and were large and heavy, requiring users to carry parts on their back. During World War 2 in 1942, improved designs were developed and helped with communication efforts. Over time, walkie talkies became smaller, cheaper to produce, and more accessible to the public and everyday consumers. Modern walkie talkies are compact and fit in the palm of your hand, with a variety of affordable options available from retailers like TBS Electronics.
