WZTI (1290 AM) is a commercial radio station licensed to Greenfield, Wisconsin, and serving the Milwaukee metropolitan area.
It is owned by the Milwaukee Radio Alliance, a partnership between Times-Shamrock Communications and All-Pro Broadcasting, along with sister stations 102.1 WLUM-FM and 93.3 WLDB.
The "MVP" in the call sign referred to "most valuable player", a title connected with owner Willie Davis' pro football years with the Green Bay Packers.

[7] On January 22, 2008, Good Karma Broadcasting, owner of WAUK, purchased Christian radio station WRRD (540 AM) from Salem Communications.
It moved WAUK's sports format to the full-time signal on February 12, casting doubt on the nighttime simulcast agreement with WMCS.
[8] On June 30, 2008, WMCS began airing its own content, consisting of blues and urban gospel programming, in addition to Al Sharpton's daily talk show.
On November 1, 2014, WZTI dropped the adult standards format and began stunting with Christmas music, calling itself "100.3 The Elf".
On December 25, 2014, at 5 p.m., after playing "Rockin' Around the Christmas Tree" by LeAnn Rimes, the station flipped to rhythmic oldies, branded as "The Party 100.3 FM & 1290 AM".
Prior to its purchase of WMCS in 1988, All-Pro Broadcasting owned WAWA (1590 AM), a 1,000-watt daytime-only AM station licensed to West Allis, Wisconsin.
