Answer 2

MP4 is short for Moving Picture Expert Group-4. First published in 1998, MPEG-4 or MP4 was designed to encompass all the features that were part of earlier releases of MPEG files, and add a few more that would prove helpful with the advancing online technology of the day. As a standardized group of video and perceptual coding formats, MP in general quickly became a hit with the average Internet user. The introduction of MP4 made it possible for the audience to continue growing by providing quicker, faster, and higher quality broadcast media for the average user.



So great was the success of MP4 that by 1999, it was considered the gold standard for all types of streaming and broadcast applications online. The functionality of the format was such that programmers were able to easily make use of MP4 on web sites and in various other applications. Businesses found it to be a great sales and marketing tool, and residential users also had a great time viewing, swapping, and even creating their own streaming media in the MP4 format.

Because MP4 was a reliable application that required a relatively low amount of bandwidth, just about everyone could take advantage of using the tool. This was especially true as technology made it possible to create more powerful desktop and laptop systems that had a larger hard drive and could command more power. The enhancement of the speed of various types of Internet connections also helped to make MP4 more accessible to a greater audience.
