[1] Kol Mevaser was established in 2005 by Zalmen Wieder, the main news presenter on the hotline.
[1] Kol Mevaser serves as an alternative to radio broadcasting for the Yiddish-speaking Orthodox Jewish community, which traditionally shuns such media in favor of community-based information sources such as Kol Mevaser, that are presented in Yiddish.
[1] There is a wide variety of programming on the hotline, including: Interviews conducted by Yitzchok Shloma Dresnser and Hendel Breuer; community affairs with Shaul Klein, Avrohom Yakov Vozner, Pinchas Glauber and Shaya Itzkowitz ("Eliezer Krausz"); psychology with Naftali Stein; and a section devoted to religious Jewish music.
In July 2019, Kol Mevaser launched a website and app called "Yiddish24" for iOS and Android users.
The website and app offer the same content that is broadcast on the Kol Mevaser hotline.
