虽然“电视”一词在公众心目中已与通过无线电广播进行的娱乐广播联系在一起，但在处理这一主题的历史时，这样的限制似乎是不可接受的和不合逻辑的。因此，作者将他们的任务解释为一项涉及对各种方法进行广泛的历史回顾的任务，在这些方法中，视觉现象可以在一定距离内复制，但不考虑传输方法或传输过程中占用的时间。由于这种解释，文件的前半部分讨论了一些建议，这些建议的目的是以一种今天我们应该更多地与摄影电报实践联系在一起的形式，而不是与现代电视联系在一起的形式，在纸上复制原始图像。由于所有实用的照相电报或电视系统都涉及某种形式的扫描，人们将意识到这两种艺术都有共同的祖先。
Although the word "television" has come to be associated in the public mind with the broadcasting of entertainment by means of radio, such a limitation seems unacceptable and illogical in dealing with the history of the subject. The authors have therefore interpreted their task as one involving a broad historical review of the various methods whereby visual phenomena may be reproduced at a distance but without regard to the method of transmission or to the time occupied in transmission. In consequence of this interpretation, the earlier part of the paper deals with a number of proposals which aimed at providing a reproduction on paper of the original image in a form which, to-day, we should associate more with the practice of phototelegraphy than with modern television. Since all practical systems of either photo-telegraphy or television involve some form of scanning, it will be realized that both arts have a common ancestry.
