By R.W. Burns
From the 1st notions of 'seeing by means of electrical energy' in 1878 during the interval to Baird's demonstration of tv in 1926 and as much as 1940, whilst warfare introduced the improvement of the know-how to a brief halt, the improvement of television amassed approximately it an important heritage. during this meticulous and deeply researched e-book, Burns offers a balanced, thorough heritage of tv to 1940, contemplating the standards technical, monetary and social which stimulated and resulted in the institution of a few of the world's high-definition television broadcasting providers. hugely illustrated all through, this can be a significant publication within the research of historical past of technological know-how, know-how and media

I ' L L INTROOUCC AIDE? * Punch's Almanac for 1879 was the first magazine to illustrate, by means of a cartoon, a possible future application of'seeing by electricity' Both the initial proposals of Carey and Senleq were for the reproduction of still pictures rather than of moving scenes, and so not surprisingly the known techniques of picture telegraphy were adopted to some extent. Carey suggested using in one of his receiving instruments chemically prepared paper while Senleq's first receiver was to employ a tracing point of blacklead or pencil for 'drawing very finely'.
The second possibility was to employ some form of scanning procedure at the transmitter and receiver, as had been adopted in picture telegraphy by Bain, Bakewell and Caselli. 4 The use of a mosaic of light-sensitive cells at the transmitter, and a mosaic of lightemissive elements at the receiver, eliminated the need for synchronising means between the transmitter and receiver Source: Journal of the SMPE, 63, November 1954, p. 231 method and later much thought was given to scanning by Le Blanc, Nipkow, Weiller, Rosing and others.
