WSVN in Miami also served as a pioneer in local news in 1989, when the station (which adopted the format in January of that year, after assuming the Fox affiliation from WCIX (now WFOR-TV) as a result of a three-way swap resulting from CBS' purchase of WCIX and NBC's purchase of longtime CBS affiliate WTVJ) originated the "news-intensive" programming format, which in its typical structure – which has become common of Fox affiliates, particularly as a result of affiliation deals signed following the network's acquisition of NFL rights, as well as certain other stations that are either affiliated with a non-Big Three network or operate as independent stations in recent years – mixes newscasts in traditional time periods with those in non-traditional ones (most commonly, in time periods that the major networks fill with national morning and evening news programs or prime time programming).
