The marketing of Wrigley Field goes back to P.K Wrigley in the early fifties. The announcers would refer to the park as the friendly confines, refer to the sunny days and come out to beautiful Wrigley Field. A part of it was probably because of poor teams and the reluctance of the Cubs to spend money. Comparing today's attendance figures with years ago can be misleading. Today tickets are sold ahead of time. The attendance figures today are the number sold,not the number there. Years ago,the Cubs would always have 15,000 general admission tickets available the day of the game. The crowds were often smaller for April,May,September,and weekend games. But weekend games back in the seventies were usually pretty full,sometimes even standing room only.
