WZZM is one of two ABC affiliates for West Michigan, and is licensed to serve Grand Rapids. Its transmitter is about 40 miles (64 km) north of other regional stations, and its over air signal is unavailable in the two southwestern tiers of Michigan. Since April 2009, however, WZZM has been available on most cable systems in Southwest Michigan, although WOTV is the ABC affiliate for that region. Until then, persons living in counties beyond the access of its signal relied upon television stations in the South Bend–Elkhart, Indiana or Lansing areas for the syndicated programs that WZZM offers.
