Hermitage House Publishing contracted L. Ron Hubbard to write Dianetics, and in the first week of March, he completed Dianetics: The Modern Science of Mental Health. He also wrote Dianetics: The Evolution of a Science for magazine publication to promote and accompany the release of Dianetics.

On 9 May 1950, L. Ron Hubbard released Dianetics, and on 18 June 1950, it appeared on the New York Times bestseller list where it remained for 28 consecutive weeks, thus launching a national movement that quickly became the fastest growing movement in the U.S.

On 7 June, L. Ron Hubbard delivered his first recorded lectures on Dianetics in Elizabeth, New Jersey, where the Hubbard Dianetics Research Foundation was formed.

On 10 August, after moving to a new residence in Los Angeles, California, L. Ron Hubbard delivered a Dianetics lecture to a sold-out crowd of over 6,000 people at the Shrine Auditorium.

Through the remainder of the year, L. Ron Hubbard continued to tour and speak in major cities. By the end of December, he had delivered over one hundred lectures while crisscrossing the country.

The Dianetics Professional and Standard Procedure Lectures and Transcripts: November 1950

Following six months of coast-to-coast travel, lecturing to the first Dianeticists, L. Ron Hubbard assembled auditors in Los Angeles for a new Professional Course. The subject was his next sweeping discovery on life—the ARC Triangle, describing the interrelationship of Affinity, Reality and Communication. Through a series of fifteen lectures, he announced many firsts, including the Spectrum of Logic, containing an infinity of gradients from right to wrong; ARC and the Dynamics; the Tone Scales of ARC; the Auditor’s Code and how it relates to ARC; and the Accessibility Chart that classifies a case and how to process it. Here, then, is both the final statement on Book One Auditing Procedures and the discovery upon which all further research would advance. The data in these lectures was thought to be lost for over fifty years and is only available in student notes published in Notes on the Lectures. The original recordings have now been discovered making them broadly available for the first time. Here, also, is both the final statement on Book One Auditing Procedures and the discovery upon which all further research would advance. Life in its highest state, Understanding, is composed of Affinity, Reality and Communication. And, as L. Ron Hubbard said, the best description of the ARC Triangle to be found anywhere is in these lectures.
