17. The system of claim 13 wherein said trusted time and date source is the internal clock of said instruction file server computer.

18. The system of claim 8 wherein said content file is divided into two or more file segments prior to transmission from said content file server computer to each of said target viewers'"'"' client computer and is reassembled upon receipt at said client computer.

19. The system of claim 18 wherein the number and size of said file segments is based on a combination of factors selected from the group of factors consisting of:

bandwidth available to said client computer, processing capabilities of said client computer, size of said content file and the level of traffic on said electronic communications network.

20. The system of claim 8 wherein said transmission of said content file server computer to each of said target viewers'"'"' client computer takes place asynchronously over a set time period.

21. The system of claim 20 wherein said set time period is based on a combination of factors selected from the group of factors consisting of:

bandwidth available to said client computer, processing capabilities of said client computer, size of said content file and the level of traffic on said electronic communications network.

22. The system of claim 8 wherein said content file is displayed to said viewer at each of said target viewers'"'"' client computer by means of a pre-installed software application compatible with said content file.

23. The system of claim 22 wherein said pre-installed software application is an application selected from the group consisting of:

a word processor, a picture viewer, a web browser, a text file viewer, a multimedia player, an mp3 player, a streaming audio player and a streaming video player.

24. The system of claim 8 wherein said content file is stored at each of said target viewers'"'"' client computer in an encrypted format.

25. The system of claim 8 wherein said content file is automatically erased from each of said target viewers'"'"' client computer after playback.

26. The system of claim 12 wherein:

said exact playback time and date is identical for two or more of said target viewers; and

the internal clock of said two or more target viewer'"'"'s client computers is synchronized with that of a trusted time and date source;

so that said content file is played back simultaneously at said exact time and date to said two or more target viewers.

27. The system of claim 8 wherein said one or more target viewers is selected from among said plurality of viewers on the basis of demographic factors.

28. The system of claim 27 wherein said demographic factors are selected from the group of factors consisting of:

age, geographic location, income, race, gender, occupation, language spoken, ethnic group and internet usage patterns.

29. A computer-based multimedia content delivery, distribution and playback system comprising:
