Many newspapers in the past few years have cut down their coverage of smaller companies considerably -- their reader surveys show that there is virtually no interest. I don't know if this policy is still in effect, but a few years ago, the L.A. Times stopped covering anything that was there for only one or two nights. This nearly eradicated coverage of local modern dance companies, and probably smaller ballet companies as well. The logic is that by the time the review is printed, the company will be gone, so there's no point in a review (which, IMO, ignores one of the great responsibilities of a newspaper, i.e., to chronicle the artistic life of the community it serves). Yet they'll turn around and say they aren't in the business of being a booster and selling tickets -- which, I think, contradicts that logic.
Another problem shared by the L.A.Times and Washington Post (which I know a bit more about as I've written for them for more than 20 years) is that they see themselves as national and not local newspapers, and therefore have more stringent standards for what is reviewed. What was once called a "civic" company, or a paraprofessional (half student, half professional) company will not be reviewed. The question is, "is this worth our attention" -- it's the same question a nightly newscast editor might ask. If it's of interest to the local community only, it won't make the cut.
While in a smaller city, a small company may get coverage because it's of civic interest -- everybody's kids dance in it -- and so a tour to anywhere out of town is Big News, that's not the case in larger cities.
It's a problem. But the only way things are going to change is if readers WRITE THE NEWSPAPERS AND TELL THEM THEY WANT TO READ ABOUT DANCE!!!!! Be specific. Complain. "So and so was not covered." "Why did you cover only opening night and none of the cast changes?" "Why didn't you write about Our Local Ballet Company's First Trip Abroad?"
Call. Call the newspaper and ask for the Style or Calendar or whatever section the arts coverage is in. You'll get a copy aid whose job includes handling phone calls. (Or call the critic him or herself; they'll transfer you to that line.) I think talking to the phone answerer may be better, because often the critic wants to cover the event, but isn't given the space.
Write letters, not to The Editor, but the editor of Style, Calendar, etc. Then it's in writing. Try to get your friends to do it too -- everyone in your studio, or your child's school.
With all respect to Frederick Douglas, who gave this advice in a far different cause, "Agitate, agitate, agitate!"
