The stylized "tv5" portion of this logo was also used for the logos of four sister stations that were also on analog VHF channel 5: WTVH, KPHO-TV, KVVU-TV and KCTV. WNEM continued using the "5" portion of this logo until 2004 (see below), long after the each of those other stations had discontinued using the stylized "tv5" logo (WTVH doing so after being sold by Meredith for example).
In 1986, the classic "5" logo was incorporated into a new "Triangle 5" logo, with the triangle usually appearing in green. Variants with an orange-green gradient triangle and with a gray triangle also were known to exist, as seen below.
On January 16, 1995, WNEM switched to CBS after having been an affiliate of NBC since the station's sign-on, as part of a larger deal between Meredith and CBS that also saw KPHO affiliate with that network. Coinciding with the affiliation swap, the triangle in the "Triangle 5" was recolored red which then became the sole color of the triangle up until it was retired.
In mid-2004, WNEM retired the "Triangle 5" logo and with it the classic "5" that had been used since 1971 and introduced a new "boxed 5" that incorporated the CBS Eye logo. The "5" and color scheme from this logo were then adapted into the logo of newly-acquired AM radio sister WNEM (since sold off, now WHHQ).
