   <abstract xml:lang="ru">
    <p>Исследована история продвижения американским радиоинженером Ли де Форестом инноваций беспроводного телефона на рынке услуг. Рассмотрена первая публичная демонстрация трехэлектродного аудиона де Фореста в Бруклинском институте искусств и наук в 1907 г. Показано значение конденсатора Мосцицкого в создании мощных передатчиков для дальней беспроводной связи. Подробно описана разработанная де Форестом телефонная дуговая система связи, которая была использована в первых сеансах радиовещания в начале десятых годов XX века в США.</p>

    <p>The history of the promotion of the wireless telephone innovations on the service market by the American radio engineer Lee de Forest is investigated. The first public demonstration of de Forest's three-electrode audio at the Brooklyn Institute of Arts and Sciences in 1907 is considered. The importance of the Mościcki capacitor in the creation of powerful transmitters for long-distance wireless communication is shown. The telephone arc communication system developed by de Forest is described in detail, which was used in the first broadcasting sessions in the early tens of the 20th century in the United States.</p>
