Page "John Logie Baird" Paragraph 16

Baird's television systems were replaced by the electronic television system developed by the newly formed company EMI-Marconi under Isaac Shoenberg, which had access to patents developed by Vladimir Zworykin and RCA.

Similarly, Philo T. Farnsworth's electronic " Image Dissector " camera was available to Baird's company via a patent-sharing agreement.

However, the Image Dissector camera was found to be lacking in light sensitivity, requiring excessive levels of illumination.

Baird used the Farnsworth tubes instead to scan cinefilm, in which capacity they proved serviceable though prone to dropouts and other problems.

Farnsworth himself came to London to Baird's Crystal Palace laboratories in 1936, but was unable to fully solve the problem ; the fire that burned Crystal Palace to the ground later that year further hampered the Baird company's ability to compete.
