Interlingue
Cosmoglotta B stopped publishing after 1950, and Cosmoglotta A was published less frequently. Other bulletins in Interlingue continued to appear during this time. Barandovská-Frank believed that the decrease of interest in Occidental-Interlingue happened at the same time as generation that was first drawn to it from other planned languages was getting older (translated from Esperanto):Most of those interested in Interlingue belonged to the generation that became familiar in turn with Volapük, Esperanto and Ido, later on finding the most aesthetic (basically naturalistic) solution in Occidental-Interlingue. After that, many moved to IALA's Interlingua, which however did not prove to be much more successful despite the impression its scientific origin made, and those who remained loyal to Occidental-Interlingue did not succeed in giving their excitement to a new generation.
