After a nearly 20-year hiatus, the beloved kids’ show “Reading Rainbow” is returning to a new generation of children and parents who grew up watching the series. The new iteration of “Reading Rainbow” will be hosted by digital creator Mychal Threets, also known as Mychel the Librarian, on TikTok. The news of a “Reading Rainbow” revival comes at a tumultuous time for public media, a jarring contrast to the early ’80s when the show began. That may be the best path forward, not only to meet and inspire a new generation of readers but to survive a shrinking public media landscape. While things may seem grim for public media, the revival of a beloved series like “Reading Rainbow” offers a familiar hope, a theme that often resonated with the original.
