Warning!! Poor examples ahead!!!!
Among other series are popular web-only series that air on a regular schedule, with each episode archived for later on-demand viewing.
Do we want questions about Web-Only series on M&TV.SE, even though technically these aren't TV Series but Web Series?
(again note, my examples are poor as there aren't really many questions you can get out of these series nor do I know of many web series, but I'm sure everyone here gets the point.)
