Jam the signal

Origin

The concept of 'jamming' signals arose in the early 20th century with the advent of radio technology, evolving from the physical act of forcing something into a space to cause a stoppage. As radio became a critical tool, particularly in military contexts, the term was quickly adopted to describe the deliberate act of transmitting powerful interfering signals to block or disrupt enemy communications. This form of electronic warfare gained prominence during World War II and the Cold War, when nations invested heavily in technologies to silence or confuse adversary broadcasts, making 'jamming the signal' a vivid and vital tactic in the invisible battle of information.
