From what I remember, individual publishers started it, but they used a combo of cd-based drm (which would install rootkits on your pc and sometimes kill your cd drive) and online activation of your key to your account. Steam just made a much less invasive system that lets you access your purchases easily instead of making it risky and hard.
Ive had this argument with people multiple times and it ALWAYS boils down to, Steam is too successful and no one else wants to compete with what steam is actually doing right.
