WDIO-DT
WDIO-DT (channel 10) is a television station in Duluth, Minnesota, United States, affiliated with ABC and owned by Hubbard Broadcasting.WIRT covers areas of Minnesota's Iron Range (including Grand Rapids, Virginia and Chisholm) that receive a marginal to non-existent over-the-air signal from WDIO, although there is significant overlap between the two stations' contours otherwise.Befera sold channels 10 and 13 to publishers Harcourt Brace Jovanovich in 1977,[6] but remained as president and general manager.This resulted in power outages in Duluth, causing WDIO, KDLH and KBJR all to lose their signal at times.[7] At the end of September 2017, WDIO/WIRT added Ion Television programming to their third subchannels, and all three signals now run in 720p high definition.WDIO and KSTP team up when breaking news happens (example: the I-35W bridge collapse in Minneapolis) or for major election debates.At some point in late 2010 or early 2011, WDIO became the third station in the Duluth area to broadcast its local newscasts in 16:9 enhanced definition widescreen.
