How it spread

Trace the origin

Robbins's social video and podcast preceded the book. Oprah promoted it before publication, then readers, TV interviews and criticism extended its circulation. BookScan counted 2.8 million US print sales in 2025; the publisher now claims over 11 million copies.

Documented milestone; not a measured attention peak. Dates use the stated precision; chart positions are date anchors.
