The 741 is obsolete... almost nobody uses it anymore. In terms of a jellybean opamp, I would guess that the LM358 and friends (LM321, LM324, and modernized rail-to-rail CMOS descendants) are quite a bit more popular.
The bipolar LM358 family is also pretty much obsolete by modern standards (plenty of nicer rail-to-rail amps available), but you can't beat them on price since they've been second sourced by practically every analog company in the industry.
Consider something like the 741. In fact, let's consider the single opamp IC family against the 555 family (including 556 and the rest).
I bet you 55x is nowhere as popular as those.
