Radio 1 tends to focus on serious work (as the moderators see it), namely on alternative and independent music of all genres (electronic, rock, jazz, reggae, ambient, etc.) rather than pop-style music. They officially began broadcasting in the spring of 1991 as the first Czech privately owned commercial radio.
Radio 1 has about 30 special shows including Blue Train (jazz session), CD Nonstop (a whole CD recording is played every day), Film o páté ("five o'clock film" - current movies program), French Connection (news from the alternative French music scene), Hard Music (heavy metal and related music program), Hitparáda Radia 1 ("the hit parade of Radio 1" - foreign music top 15), Knižní servis ("the book service" - new books discussion), Reggae club (reggae), Shadowbox (news from the d'n'b scene), Velká sedma ("the great seven" - Czech music hit parade), Všechny hudby světa ("all music of the world" - world music program) or Zátiší ("the still life" - discussion program with invited guests). It is also one of the few Czech radios to have shows held by English speaking moderators.
