Examples
There are many examples of multimedia in the marketplace today, but I will only focus on three different types:  DVD's, Personal Computers, and Video Games.

Implications
Multimedia is important to us because it is everywhere.  We are always mixing different media such as sound, video and text.  It is happening in many technologies we use such as the examples above. 

Multimedia makes technologies more useful to consumers.  For example, personal computers are not just used for writing text papers.  They incorporate many types of media and this can save consumers money.  For instance, instead of having a TV, Stereo, and a DVD player you can have it all in a personal computer if you choose.  Which is also an example of convergence. 

Other Thoughts
I only see advantages of multimedia.  When used correct it can aid in education or simply entertain consumers.  The trend makes computers, DVD players and video games all possible.  I feel this megatrend is most like convergence because they're both bringing stuff together.  Convergence is more bringing different products such as a TV and a VCR together whereas multimedia is combining the actual media. Multimedia is an unstoppable trend because people are always going to mix sight and sound.
