But most important was that BMI took public domain works and made arrangements of them, which they gave away for free to their subscribers. So that in 1940, when ASCAP threatened to double their rates, the majority of broadcasters switched to BMI.
Det viktigaste var dock att BMI tog verk ur allemansrätten, - gjorde arrangemang av dessa och gav bort dem gratis - till sina abonnenter. Så när ASCAP 1940 - hotade att dubbla sina taxor - bytte större delen av sändarbolagen till BMI.
