Advances in technology and its ease of use accompanied by reducing costs have increased the effectiveness of messaging and made it more affordable. It can be used for promotional or information purposes and delivered communally or to individual screens, in the whole building, or by text messages via mobile phone (SMS).

The most suitable method of delivery is driven by the nature of the message and whether this is long or short term. Long/short term examples of this are fixed menu/daily specials, fitness class timetable/"2 spaces in class starting in 15 minutes". All options are changeable by direct input and can be overlaid on selected screens or a TV channel carrying longer-term information; in some cases it may be more appropriate to deliver these by text (SMS).
