710 began operations in 1946 as WKRG (for Kenneth R. Giddens, owner). WKRG-FM and WKRG-TV 5 were spawned from this AM. Has always been an adult-appeal station, CBS affiliated, MoR music, with talk shows. Evolved to all-talk in the 80's as FM made music on AM unprofitable. Calls changed to WNTM (News Talk Mobile) when station was sold in the early 90's. Now co-owned with WPMI-TV 15.

Due to interference from Cuba stations at night, the station applied for (and received an allocation  for) moving to the expanded band, but they let the permit lapse without building out the new facility.  It was for 1660 kHz, stereo.

In August 2006 it was rumored that the station would be changing calls, and it did happen: the station is now WPMI, to reflect the fact that they share a newsroom with WPMI-TV, as well as the same owners.  In the summer of 2007 the calls changed again, back to WNTM (News Talk Mobile).
Also, the station has an application pending to increase daytime power to 6 kW and nighttimes to 2.1 kW, both with directional antennas.

The station began rebroadcasting on WRKH-FM's HD-2 subchannel sometime in the summer of 2010.
