An aside: Wikipedia provides this helpful tidbit from the early days of the magazine when it was targeted at children: "Munsey found that targeting children had been a mistake, as they did not stay subscribed for any length of time, since they grew out of reading the magazine. Additionally, children did not have much money to spend, which limited the number of advertisers interested in reaching them."
