Overspill TV or radio refers to the phenomenon of a broadcast signal extending beyond its intended coverage area, resulting in unintended viewers or listeners tuning in. This can occur due to technical issues, atmospheric conditions, or intentional signal boosting. Overspill can also refer to the overflow of content from one channel or station to another, often due to scheduling conflicts or network interruptions. In the world of media, overspill can lead to unexpected audiences and increased viewership, but it can also cause disruptions and confusion for both broadcasters and viewers.
