Normally how many issues can last an ongoing book?, I miss those series that exceeded 50 issues or they were able to go beyond the 100 or more issues and that's very respectable.

An ongoing title can go as many issues as people buy in sufficient quantities.

It’s a lot more difficult today than it was back then to create a long sustained run, because there are so many more titles in the marketplace, as well as so many more choices for your entertainment dollars.
