Few companies have the legacy of Houghton Mifflin Harcourt. Founded in 1832, it has introduced the world to literary greats from Ralph Waldo Emerson to Philip Roth, classic culinary and reference titles from Betty Crocker to Peterson Field Guides, and beloved children’s stories from Curious George to The Lord of the Rings. HMH’s iconic, best-selling titles are treasured by readers throughout the world. But HMH hasn’t succeeded for nearly two centuries solely by sticking to the classics. With more than 4,000 employees worldwide, HMH is a leading provider of educational materials, with its content reaching nearly 50 million students across 150 countries every year. HMH’s pre-K–12 offerings make up the largest portion of the $1.37 billion company. In a time when many in the publishing industry are experiencing the pain of downsizing and consolidation, HMH succeeds by constantly evolving, changing, and innovating. Today, school curriculum looks very different than it did even just a few years ago. We live in a new era in which we all want instant information. Our cars talk to us, our toothbrushes send reports to our dentists, our watches analyze our workouts and how we slept — and we receive this feedback instantly. As customers, we can’t even imagine an app taking weeks to report back how we slept, waiting a month for an exam score, or owning a history book that doesn’t include the most recent election results. Those scenarios made sense in a time when we wrapped textbooks in brown paper grocery bags, but it doesn’t make sense today. HMH observed the change early and evolved to deliver content with continuously updated information, features, and functionality to where its readers engage — in an app, on a platform, on an iPad, or on an iPhone or an Android device. No longer tethered to textbooks, students can do homework on the way to soccer practice. Interactive offerings with embedded video or gaming technology can cater to different learning preferences and allow students to engage on a deeper level. Content rendered digitally contains metadata so it can be searched or re-sequenced, making it customizable. And reviews are built into programs and happen in real time, which has given rise to adaptive learning — a new technique that allows educators to meet students where they are. These advances are transforming education and transforming the company.
