K-LOVE

The massive K-LOVE radio network began in 1982 with a single station--91.9 KCLB--in Santa Rosa, California.  They started adding new stations in 1988 and began broadcasting online in 1998.  K-LOVE's website doesn't say how many total stations and translators their network is made up of, but Wikipedia puts the number at over 440 across 47 states.  klove.com is the sixth-most online-streamed station in the world.
