Zenith Radio seriously experimented with transmitting thoughts via radio waves

Evidence

In the mid-1930s, for instance, Zenith seriously tested whether it could transmit thoughts to its listeners via radio waves. “On these programs,” it said of its telepathy experiments, “the listeners will be taken where no living person has ever been.” — Tim Wu, The Attention Merchants, 505

• QUESTION: What exactly were Zenith’s telepathy experiments? Could make for a great rabbit hole on 1930s fringe broadcasting.
