Samsung is more successful today but Sony has more impact, tbh. Remember walkman, discman, trinitron, bravia tvs, the dualshock controller and the playstation?

Sony revolutionized the way we listen to music tbh.. Samsung just copied sonys steps. (apple anyone? Deja vu)

This.

Sony has been in these streets since the 40's, They made the first (commercally popular) transistor radio.
