Special features

A list of special features, also referred to as "bonus features", specifically created/added for/by the official Star Trek franchise for (first-time) inclusion on the various Star Trek home video format releases, which, aside from the (usually franchise-produced) documentaries proper, also include publicity/promotional material (notably theatrical teasers and trailers), outtakes (mostly in the form of the so-called "blooper reels"), deleted scenes, production (still) galleries, hidden features (aka "Easter eggs"), separate music scores, text and audio commentaries when included on/in the format release. In more recent years these have also become known as as "Value Added Material" ("VAM"), so coined by VAM producers Robert Meyer Burnett and Roger Lay, Jr..
