Slovenský rozhlas

Slovenský rozhlas ("Slovak Radio") or SRo was a state-owned nationwide public-service radio broadcaster in Slovakia. It was headquartered in Bratislava in a building shaped like an inverted pyramid, which currently serves as RTVS radio's headquarters.

History
SRo began broadcasting from Bratislava, then in Czechoslovakia, twice per week on 3 August 1926 and then daily from 2 October 1926. The broadcaster also managed the Slovak Radio Children's Choir, founded in 1953, and the Slovak Radio Symphony Orchestra (SOSR), founded in 1929 as the Czechoslovak Radio Symphony Orchestra.

As a means to improve the finances of the state-owned public television broadcaster Slovenská televízia (Slovak Television), on 1 January 2011 SRo merged with Slovenská televízia to create Rozhlas a televízia Slovenska (Radio and Television of Slovakia).

SRo was a full member of the European Broadcasting Union between 1993 and 2011.
