"These glass insulators reached their peak use between 1920-1950. By the end of the 1950s, electrical companies had begun transitioning to porcelain insulators - a transition which was complete by the end of the 1970s. This meant that most of the insulators which collectors hunt down today come from the early-20th century. In terms of modern telecommunications, most electrical systems use cable, which doesn't need insulators at all, meaning that there's less of a need for these insulation technologies." - Megan Cooper, "Love to Know" 2021
