On November 7, 1994 WXYC (89.3 FM Chapel Hill, NC) became the first traditional radio station to initiate broadcasting on the Internet. WXYC used an FM radio connected to a system at SunSite, later known as Ibiblio, running Cornell's CU-SeeMe software. WXYC had begun test broadcasts and bandwidth testing as early as August, 1994.
WREK (91.1 FM, Atlanta, GA) started streaming on the same day using their own custom software called CyberRadio1. However, unlike WXYC, this was WREK's beta launch, and the stream was not advertised until a later date.
