From the early-mid 2000s, PBS Kids aired a series of bumpers called "Letter Bus" it features alphabet letters on a bus. It was made by Bob Shea. By the late 2000s, most PBS stations stopped airing this, although some stations still air this along with other old PBS Kids bumpers like "CET", "KQED", and "WFWA" alongside other PBS stations.
