Houghton-Mifflin Harcourt—now called HMH—updated its logo to reflect how fast education is changing. Today, textbook publishing goes well beyond printed volumes and workbooks. The company previously known as Houghton-Mifflin Harcourt—the publisher behind such childhood favorites as Algebra: Structure and Method—just renamed itself HMH and got a new logo. The rebrand, by the creative agency Lippincott, is part of a pivot that aims to reflect the way students learn today.
