Dashes are something I notice. A lot. I used to prefer em dash for parentheticals, but lately I find space en dash more readable. That is a poor reason. Fail. I actually prefer to write British English, which is technically incorrect American. The destruction of Latin roots irks me. E.g. 'centre' vs 'center.' The Latin root tells you a 'center' is a 'person who cents.' English is bad enough without destroying what little virtue it has left. I'd love to be an editor or typographer. Such a shame they're low-demand fields with lower pay.space en-dash space or just em-dash
the original writer had em dashes in between the dates
Yep, always wrong. Hyphens are technically permissible, but I strongly prefer en dashes. the client wanted "premier" because it would allow the table column to be smaller
Except the word is question refers to the "premiere date" of television shows.
