2. Digital video
When film first came around it was all analog and used physical film which was light
sensitive. A old film camera would have a large box sat on top which would have the
film tape and would move it from one reel to another. Digital film cameras record
directly onto a hard drive which would be considerably smaller than a box of film
tape on top. The first film to be completely made with digital recording equipment
was Star Wars episode One the phantom menace and episode II: attack of the clones
using a Sony HDW-F900, and both were shot with full hd film.

4. On Demand
Video on demand are systems which allow users to select and watch/listen to video
or audio content such as movies and TV shows when they choose to, rather than
having to watch at a specific broadcast time. These can often also be downloaded in
order to watch at a later date, without internet access.
An example of this is BBC Iplayer, that allows you to watch shows on the BBC
network at any time.
The first video on demand (VOD) systems used tapes as the source of video streams.
GTE started as a trial in 1990 . By 1992 VOD servers were supplying previously

3D tech has existed for a long time, The earliest confirmed 3D film shown to an
audience was The Power of Love, which premiered at the Ambassador Hotel
Theater in Los Angeles on 27 September 1922, using a blue green two strip method,
where anaglyph glasses of two colours created the illusion of depth.
Past the 2000’s, 3D made a small resurgence as a gimmick in films such as “Spykids”
(2003) or “Sharkboy and Lavagirl” (2005) but did not see mainstream resurgence
until the late 2000’s. Many credit the resurgence of 3D to James Cameron’s “Avatar”
That released with 3D options and used new 3D technology, such as sleaker black
glasses and new 3D projectors installed in many theaters.
