"Prior to tape recording technology, most television programs were broadcast live with no recording or archiving. Film was used for some events and broadcasts, but it was expensive. This fundamentally changed the approach of television stations, enabling them to record shows, and also to archive and re-broadcast them as repeats. However, VCRs also shook up the entertainment industry in other ways. Actors and writers went on strike in 1985 over the percentage paid to them for work released on video. VCRs were also blamed for reducing movie theatre attendance and putting a damper on box-office takings over the 1985 summer season."
