Spain World Cup broadcast latency explains why neighbours hear the goal first

During the 2026 World Cup, Spain’s goal was heard by some neighbours before it appeared on their TV screens. The difference is due to broadcast latency – the time between the live action in the stadium and the moment it reaches the viewer.

Radio on FM/AM transmits almost instantly, while digital radio (DAB) can add a few seconds and internet audio may introduce 20‑50 seconds of delay. Conventional terrestrial, satellite or cable TV typically lags 5‑20 seconds, and streaming services often add the longest buffers, resulting in delays of up to 50 seconds. The UK regulator Ofcom estimates these ranges and notes that buffering is used to prevent interruptions.

Because each platform processes the signal differently – from production and compression to transmission and decoding – viewers using different services can experience the same goal at different times, sometimes hearing it on the radio before it appears on television or a streaming app.
