Thats just a callsign, all callsigns in the US start with K, W, AAA-ALZ or N, commercial broadcast services use K and W exclusively. Commercial Broadcast stations are generally three or four letters, with a suffix like -FM, -TV, -DT, -LP, or -FM1, its even possible to have multiple suffixes stacked KWWW-LP-FM1.
Translators can have even more characters and are a combination of numbers and letters.
Experimental stations are generally W or K a region digit, and three letters starting with X, these are issued out of the pool of callsigns used for amateur radio stations.
Buiness band and GMRS licenses use the same format, generally three or three letters starting with K or W, and three or four numbers.
