Parallel presentation includes the simultaneous presentation of two different forms of the same information (for example aural dialogue and subtitling on a film); related and/or explanatory information (e.g. text captions under graphics, titles and text headlines on TV news); various iterations of information that is the same in kind but unique in detail -- (e.g. TV guides).

In real terms, most online navigation (e.g side and top/bottom navigation bars) is parallel.
