series of comic operas by Gilbert and Sullivan and were followed by the 1890s with the first Edwardian musical comedies. The first play to achieve 500 consecutive performances was the London comedy Our Boys by H. J. Byron, opening in 1875. Its astonishing new record of 1,362 performances was bested in 1892 by Charley's Aunt by Brandon Thomas. After W. S. Gilbert, Oscar Wilde became the leading poet and dramatist of the late Victorian period. Wilde's plays, in particular, stand apart from the many now-forgotten plays of Victorian times and have a closer relationship to those of the Edwardian dramatists such as George Bernard Shaw, whose career began in the 1890s. Wilde's 1895 comic masterpiece, The Importance of Being Earnest, was the greatest of the plays in which he held an ironic mirror to the aristocracy while displaying virtuosic mastery of wit and paradoxical wisdom.

Other genres include nonsense verse, poetry which required a childlike interest (e.g. Lewis Carroll's "Jabberwocky"). School stories flourished: Thomas Hughes' Tom Brown's Schooldays and Kipling's Stalky & Co. are classics. Rarely were these publications designed to capture a child’s pleasure; however, with the increase in the use of illustrations, children began to enjoy literature and were able to learn morals in a more entertaining way. With the newfound acceptance of reading for pleasure, fairy tales and folk tales became popular. Compiling folk tales by many authors with different topics made it possible for children to read literature about many topics which interested them. There were different types of books and magazines written for boys and girls. Girls' stories tended to be domestic and to focus
