5.910 radio live
2.029 radio ultra
1.887 radio kiss fm
1.714 radio 21 live
1.464 radio manele online
From these data : the three radios that counts online are : Radio 21, Radio Romantic, Radio KissFM
Radio 21 is far the winner of Romanian Internet community search, 5 times bigger online than Romantic (a very nice Radio indeed) and 25 times bigger than KissFM, the real competitor in the market.
I wonder where is EuropaFM in online, because they promote a lot their webiste on-air.
I think the visitors from radio self-promotions are equal for Radio21, KissFM and EuropaFM, but the difference in visitors is made by the brand awareness, where Radio 21 beats them all.
BONUS : Rita Rita, a melody promoted by Radio 21
