By late 1999, WAMI had grown into its role as the "flagship station" of what was to become the USA Broadcasting Network, comprising thirteen stations scattered around the country in major U.S. cities, twelve of which were former HSN affiliates. All of these stations, which were owned by Barry Diller, were to gradually be converted to follow WAMI's format, called "CityVision". The "CityVision" concept was based on Diller's theory that local programming was being ignored on most broadcast stations, and that the general public wanted a sense of what is going on in their communities on television. A scaled-down version of the format was adopted by USA Broadcasting-owned sister stations KHSX-TV in Dallas (which became KSTR-TV and rebranded as "K-Star 49"), WHSH-TV in Boston (which became WHUB-TV and rebranded as "Hub 66"; it is now WUTF-TV) and WHOT-TV in Atlanta (which rebranded as "Hotlanta 34"; it is now WUVG-TV). The rest of the former HSN-affiliated stations owned by USA that were due to be converted were WHSE-TV (now WFUT-DT) and WHSI (now WFTY-DT) in the New York City market (whose calls were to be changed to WORX and rebranded as "The Works" upon the format change), WEHS (now WXFT-DT) in Chicago (which was to become WNDE and be rebranded as "Windy"), WQHS-TV in Cleveland, KHSC-TV (now KFTR-DT) in Los Angeles (whose calls were to be changed to KLIK and be rebranded as "Click"), WHSP (now WUVP-DT) in Philadelphia, WHSW (now WUTB) in Baltimore, KHSH (now KFTH-DT) in Houston and WBHS (now WFTT-DT) in Tampa.
