Electronicam

It was developed by James L. Caddigan for the DuMont Television Network in the 1950s, before electronic recording on videotape was available.

The DuMont Television Network used Electronicams in 1955 to produce most of its studio-based programming since it had (except for occasional sports events) discontinued use of coaxial cable and microwave links to connect stations.

The "Classic 39" episodes of The Honeymooners aired during the 1955–56 television season on CBS were shot with Electronicams, which meant they could be rerun on broadcast TV and eventually transferred to home video.

Without Electronicams, the half-hour The Honeymooners episodes in the 1955-56 season may have been broadcast live and only exist as poor-quality kinescopes.

Also, around 1956 British producer J. Arthur Rank brought three Electronicams to the United Kingdom to experiment but eventually was disappointed with the picture quality.
