First cable networks In 1992 TVS Holding Brasov was developed by Zoltán Teszári, Ioan Bendei and other businessmen. The company offered cable television services in
Brașov and
Timișoara. In 1993, Zoltán Teszári co-founded Kappa cable company in Bucharest. In 1996, the shareholders decided to divide the Kappa network into two equal parts. Half owned by Zoltán Teszári merged with Analog CATV SA cable company in Bucharest. The other half was bought in 2000 by
Astral Telecom, which in 2005 was merged with
UPC Romania (now
Vodafone Romania). This separation of the company led to the division of the areas in Bucharest between the two companies for 10 years.

Romania Cable Systems S.A. (
RCS). Same year it is established
Romania Data Systems S.A. (
RDS) which offers internet services.

The company entered Hungary in November 1998 after buying 15 small and medium cable companies in
Budapest and 3 other cities. Between December 1999 and January 2000, the first cable networks were acquired in
Slovakia, where Slovakia Cable Systems (SCS) was 95% owned by RCS. In April 2000, the project to build a 4,200 km national
fiber optic network was initiated. In 2003, after the liberalization of the market, the
