A free preview (also called a free preview weekend and sometimes referred to under the portmanteau "freeview") is a stunt programming concept in which a pay television service or channel tier is exhibited without signal encryption to customers of a multichannel television provider (cable, satellite, IPTV or over-the-top MVPD) at no cost for an extended time period. Such events, which typically run anywhere from two days to one month on average, are held mainly to incentivize subscribers into purchasing the service that is being transmitted during the applicable timeframe.
