In celebration of the 75th anniversary of Dr. Seuss’ first children’s book, Oceanhouse Media has released an interactive omBook app version of the book, And to Think That I Saw It on Mulberry Street. First published in 1937, the book recounts the tale of Marco who walks to school along Mulberry Street keeping his eyes peeled for interesting sights to share with his father, conjuring up elaborate and exciting events in his imagination as he proceeds down the street. Originally rejected by 27 publishing houses for being too fantasy based and different from typical children’s books of the time, And to Think That I Saw It on Mulberry Street ultimately became the title that launched the now-iconic Dr. Seuss series. The omBook version brings this original story to life with professional narration, background audio and enlarged artwork for each scene and also includes highlighted words and interactive images to promote reading in young children. Oceanhouse Media is an officially licensed publisher of Dr. Seuss and other children’s book titles for iOS and other mobile and tablet devices, producing interactive and educational versions of classic children’s books. And to Think That I Saw It on Mulberry Street is available from the App Store for an introductory price of $3.
