The old version used to have history with it, about radio stations. The tabs: History, Jingles, Stories

From MIT:

In addition to the “Live” option, Radio Garden has three other sections: History, Stories and Jingles. In “History,” one can find various historical uses of radio such as a news program from the World War II era or an Arabic language lesson. In “Stories,” people describe their experiences as radio listeners and how this medium allowed them to feel at home, and at the same time, connect with the rest of the world. “Jingles” section presents international examples of short-form music and sound design that are used for branding radio stations and programs.
