Why is Placidus so popular?

“It has become a cliche in the 20th century that the Placidus system later became the 19th and 20th century standard because it was the only one for which affordable tables were readily available. This is partially true, but the same thing could be said for the initial success of the Regiomantanus system.” Holden, A History of Horoscopic Astrology, p. 150.

OK, this may be a selection, but actually, it´s quite interesting stuff. Seems like Placidus was also easy to make tables of, had some good advocates and was based on an interpretation of Ptolemaeus. Now it´s almost standard stuff so most people start with it and continue to use it, a bit like Windows VS Linux :37:

This was before the internet and information wasn’t as available.

Like many standards it’s a matter of convenience and would be difficult to switch.
