End view tubes were designed with the intention of saving space at the display face. For example in aircraft and tanks where the space available for instruments and indicators is limited- there was more space behind the tubes instead of above or below. New developments quickly surpassed the refinements of end view tubes and they were basically abandoned. An LED display could be 10-15 times as dense as a nixie.
