WRVR

104.5 originally aired religious oriented programs with the call letters WTCV, later they were easy listening with the call letters WAID. On April 23, 1975, they switched formats to MOR with the call letters WQUD and were called Quad 104. It was also the sister station of WDIA (which is where the former WAID call letters—in reverse—came from).

"The River" branding is a local reference to the Mississippi River.

The station's license is currently held by Entercom Communications. It is one of six radio properties in the Memphis market held by Entercom; the others are WMC-FM, WMC-AM, WMFS, WLFP, and WMFS-FM. WRVR maintains studios in the Entercom complex in eastern Memphis. Prior to Entercom, the stations were owned by CBS Radio until 2006.

The "WRVR" call letters previously belonged to an FM jazz station in New York City broadcasting at 106.7 FM from 1961 to 1980. (That station is now WLTW.)

In October 2017, morning show hosts Mike Montana and Mandy Morgan exited 104.5 The River leaving a rare opening during morning drive on The River. In January 2018, long time Memphis radio morning show host Ron Olson, from sister station WMC (FM100), switched to mornings on 104.5 The River. His former WMC FM100 co-host Karen Perrin joins is once again his morning show partner on The River.
