It used to annoy me slightly that in order to subscribe to Billboard magazine, you had to indicate your primary industry function from a list of music and radio occupations on a reply card. I thought, "What difference does a person's job make as long as (s)he can pay for the subscription? Granted, I'm in grade school, don't have a job, and can't afford a subscription, but still, why does this matter? I'm interested in reading the music charts and columns. Is there a pecking order here? Do record company executives receive their issues a day or two ahead of those in other professions?"
Then, I looked closer and saw there was a box one could check for "music fans and audiophiles."
I still couldn't afford a subscription, but I was slightly less miffed.
