WDTW (1310 kHz, "La Z 1310 & 107.9") is a commercial AM radio station licensed to Dearborn, Michigan, United States, and serving the Detroit metropolitan area.

Seymour's "Bobbin' with Robin" show featured a music mix that foreshadowed the birth of the Top 40 radio format in playing R&B and early rock and roll artists like The Crows alongside mainstream pop stars like Patti Page.

Seymour remained with the station as it became WKNR and later became the host of Swingin' Time, a popular local teenage dance show on CKLW-TV.

Despite the power of WJBK and WXYZ and the 50,000-watt signal of CKLW, consultant Mike Joseph (best known for developing the Hot Hits format in the late 1970s) was convinced there was room for a fourth Top 40 station in Detroit and that 1310 AM could easily climb ahead of the competition.

WKNR officially launched on October 31, 1963, with the "Battle of the Giants", an attention-grabbing promotion that invited listeners to call in to vote for their favorite oldies.

The station quickly gained momentum, and in an unprecedented "worst-to-first" move, three months later "Keener" was a solid across-the-board number one in the ratings.

This happened despite a weak signal which missed most of the east side of the Detroit metro area, especially at night, although the station could be heard market-wide on its more powerful FM simulcast on 100.3 MHz.

Keener featured popular personalities like Dick Purtan, Bob Green, Gary Stevens (later of New York's legendary WMCA), J. Michael Wilson, Scott Regen, Ted Clark and Jim Jeffries.

Scott Regen's "Motown Monday" features included live concerts from the Roostertail supper club, featuring Motown legends such as the Supremes and The Four Tops Dick Purtan honed the wry, sardonic sense of humor that made him a fixture on the Motor City airwaves for four decades, first on WKNR.

WKNR's dominance was challenged when CKLW 800 AM got a makeover courtesy of consultants Bill Drake and Paul Drew in April 1967.

With 50,000 watts behind it and a lightning-fast pace based on Drake's "Boss Radio" model, The Big 8 became the number one Top 40 station in the region.

Sister station WKNR-FM 100.3, which had previously simulcast the AM programming, switched to a more adventurous progressive rock format starting in 1969.

The Keener 13 era is celebrated at keener13.com, with an extensive history, an archive of air checks and a database of every WKNR Music Guide in addition to an online tribute webcast called wknrkeener13.com.

WKNR began playing the same easy listening format that was successful on 100.3 WNIC, simulcasting its FM sister station.

AM 1310 simulcast for a short time until the decision was made in 1977, to revive the "Keener 13" brand name on its original frequency with an adult-oriented Top 40 and oldies mix and a new call sign, WWKR.

On January 21, 2010, WDTW's network, Air America Media, filed for Chapter 7 Bankruptcy and ceased live programming the same night.

The station was operated out of TSJ's facilities in Columbus, Ohio, while WDTW completed the build-out of its studio in Taylor, Michigan, and hired full-time staff members.
