Penguin says it found that follow-up research suggests that paperback readers prefer the new Premium format, and are not discouraged by the higher price point of $9.99.
Penguin says the interior of the books have been crafted with the production values of a hardcover book in mind: higher quality paper, more white space both in the margins and between the lines of text, and a larger font size throughout.
PenguinGroup (USA) CEO David Shanks said, "We're addressing the needs of our readers; our readership has changed dramatically, so it's almost hard to believe that this is the first time the mass market format has been re-engineered in the last 50 years.
PenguinGroup is the second largest trade book publisher in the world.
The PenguinGroup, with primary operations in the United Kingdom, Australia, the United States and Canada, and smaller operations in South Africa and India, is led by its CEO and Chairman, John Makinson, and is owned by Pearson plc.
PenguinGroup (USA) Inc. is a global leader also in children's publishing, through its Books for Young Readers, with preeminent imprints such as Dial Books, Dutton, Grosset and Dunlap, Philomel, Puffin, Speak, Firebird, G. Putnam's Sons, Viking, and Frederick Warne.
