In March 1922, the Improvement Era carried a short article by editor Edward H. Anderson about the exciting possibilities of the newly invented vacuum tube amplifier – those glass tubes seen inside antique radios and other early- to mid-20th century gadgets. Such tubes amplified electric signals to such an extent that for the very first time, the human voice could be heard by telephone from one coast to the other. Why, Bro. Anderson wrote, “It is not impossible that, by 1925, or sooner, the President of the Church of Jesus Christ of Latter-day Saints may be able to deliver his sermons in the Salt Lake Tabernacle and be heard by congregations assembled in every settlement of the Church from Canada to Mexico, and from California to Colorado.”
