Contemporary isn't one thing and one thing only, it is the basic style, the one-size-fits-all of design. The style of contemporary changes with the times, but our current Contemporary is a little like Swiss international meets freedom. It is usually a simple white (or colour) background with some simple text, this is the base of Contemporary from there designers branch out a bit to make it different. Sometimes they mess around with the text, they; jumble it or vary the sizes of the letters. They add a simple picture or two. Some times they would use a picture that looks like a letter in place of the letter it's self. But the key to contemporary is to keep it simple and not to clutter the page.
< This ad holds true to the contemporary style with a simple colour scheme, grid format, plain font, and is quick-to-the-point. It is simple and I like it because of that.
> This is also a classic/contemporary advert, Plain background, one image, a couple of logos, and minimal text. I live this ad because of the eye catching text "Hello", I like how they played around with the "L's" by using the signal bars from the product, and they used four signal bars in stead of two because they wanted to tell people "hey, buy our new phone and you will never have a problem finding a signal again." (totally not true, even the best phones have trouble getting a signal in the middle of nowhere).
