Magazines, journals, and newspapers are different types of periodicals. A magazine is a publication that is intended for a general audience. It's articles are usually short, with little depth. The articles are most often written by members of the magazine staff, who either write about a personal experience, or interview others about the topic of interest.
Magazines often contain lots of advertising and flashy images or graphics.
However, because they report quickly and simply on current interest topics, it is common for there to be many errors in their reporting. A journal is different from a magazine in a number of ways. First of all, they are published less frequently. A journal is often targeted for a very specific audience, and frequently published by a professional organization as a benefit to its members. The pages are often numbered sequentially through an entire year, so that, for instance, the February issue begins counting on, say, page 206.
