DVD +/-

I never understood why we have + and - DVD's. When I went to go and burn my Photos to a DVD slide show i used a - disc, but unfortunately my player is a + disc reader. Does anyone know why they made two seperate versions? I can understand them putting region codes on commercial DVDs, but the +/- disc are just baffling.
