Serial (radio and television)
In television and radio programming, a serial has a continuing plot that unfolds in a sequential episode-by-episode fashion. Serials typically follow main story arcs that span entire television seasons or even the full run of the series, which distinguishes them from traditional episodic television that relies on more stand-alone episodes. Worldwide, the soap opera is the most prominent form of serial dramatic programming.
BBC television drama
From the 1950s through to the 1980s the BBC received much acclaim for the range and scope of its drama productions, producing series, serials and plays across a range of genres, from soap opera to science-fiction to costume drama, with the 1970s in particular being regarded as a critical and cultural high point in terms of the quality of dramas being produced. In the 1990s, a time of change in the British television industry, the department went through much internal confusion and external criticism, but since the beginning of the 21st century has begun to return to form with a run of critical and popular successes, despite continual accusations of the drama output and the BBC in general dumbing down.
