Introduction +
entertainment = introtainment.
Can be used to describe the Macromedia Flash animations that appear when you visit a Web site, the point of which is to bombard your senses with flashes of light and moving words and images before you get to what you were looking for, because heaven knows editorial content in and of itself isn't cool.
Can also describe the slides featuring trivia questions on the movie screen before the feature starts, although they aren't half as entertaining as the snide comments you and your friends make about said slides.
