Celebrities and pop culture are important, but not as important as for girls. We see Finn, partially inspired by "Glee," at No. 1 and Atticus in the Top 10 thanks to "To Kill A Mockingbird." While other names - Jude, Liam, Emmett, Hudson, Arlo - have risen on the heels of popular stars, celebrity babies, and movie and TV characters - we see this influence on boys' names less pronounced than on girls'.
Boys' names are getting softer. The whole badass boys' name - Stryker, Wilder, Maverick - thing aside, we see a softening of boys' names, with vowel endings (Milo, Levi, Ezra), sibilant sounds (Asher, Dashiell, Sebastian), and choices that are derived from girls' names or can also be used for girls (Rowan, Emerson, Elliot).
