WPVI-TV signed on its digital signal on November 1, 1998. The station shut down its analog signal, over VHF channel 6, on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal relocated from its pre-transition UHF channel 64, which was among the high band UHF channels (52-69) that were removed from broadcasting use as a result of the transition, to its analog-era VHF channel 6 for post-transition operations.
