Jacob Evison is working for the BBC's research and development department to rebrand their idents for the launch of the first female Doctor Who. He has been asked to research the purpose of idents by analyzing existing examples. An ident is a short sequence shown between TV programs to identify the channel. Idents are used for identity, branding, marketing, packaging/repackaging programs, and scheduling. They represent the channel's themes and brand viewers with consistent logos and colors. As idents are shown frequently, they advertise the channel and upcoming programs. Some idents include extra information for viewers or amuse audiences between segments.
