Berkeley Publishing is preparing to launch their new high school history textbook. They contact the 15 editors that reviewed the book and ask each one to record a 20 minute supplemental lecture for each chapter using Lecture123. The textbook is to be sold with the incentive that teachers will have these dynamic, engaging lectures to share with students. Additionally, Berkeley hires a team of several college history professors who will handle incoming questions from students all over the country and respond back. Sales of this new textbook are 20% higher than similar books in the past attributable directly to the value added with Lecture123 content and collaboration.
