RCN Corporation was originally created in 1993.  It began as a cable TV overbuilder, constructing competitive cable systems in markets that already had cable service.  Most of its systems were partnerships with power companies, which provided rights-of-way on poles. 

In February 1998, RCN acquired a pair of Internet service providers, Virginia-based Erols Internet, Inc. and Boston-based UltraNet Communications to strengthen the data side of its business.  Four months later, RCN added New York Interport Communications, which served 10,000 dial-up and 500 dedicated Web hosting customers. 

In June 1998, RCN added Springfield, Massachusetts-based JavaNet, Inc., which linked high schools and colleges to the Internet.  As a result of the pickups, RCN became the largest ISP in the northeast and one of the ten largest in the country. 

In March 2006, RCN acquired Con Edison Communications (CEC).  CEC was a wholly-owned subsidiary of Consolidated Edison Inc.  It offered a comprehensive range of transport products and services designed to serve multiple classes of customers, including carriers, Fortune 1000 corporations, small and medium businesses, and Internet, cable, wireless and video companies.  CEC built and operated its own fiber optic network in the New York City.

With the acquisition of CEC, RCN created the subsidiary RCN Business Solutions.

In November, 2007, RCN Business Solutions acquired NEON Communications.   NEON, a wholly owned subsidiary of Globix Corporation, owned and operated a technologically advanced fiber optic network in twelve Northeastern and mid-Atlantic states. NEON was a wholesale service provider offering high bandwidth transport services to service providers and Fortune 100 companies.
