Here are two examples of Things That Almost Were But Weren’t: Photography (1839) and Television (1928). The first item contains a woodcut of a heliotype (being the first image of a photograph produced by non-photographic means); the second displays the method for receiving images of radio shows but is not a television.
First: The first published non-photographic image of a non-photograph or “sunpicture”, 1839
