One important such (physics) journal with display equations spanning two of
three columns is Phys.Rev. (published by APS). Moreover they sometimes
change the number of columns at such a display; all that is achieved by
their 'revtex' documentclass (standard LaTeX).

As for the virtue of such things: I personally find then hard to read.
