Educational Internet advertising is principally ads that are presented to the user usually in the form of text (such as seen on Google’s search results), static images, animations (flash for example), and video specifically to encourage them to apply for a school or institution. These display advertisements can appear either on the same page, next to, or as a popup and are known as periodicals. Text advertisements are used when image types are unavailable or are seen as being more appropriate, can be seen on search engines as well as websites. The advantage to using these is that they load quickly compared to image ads. Popular internet advertising companies are Google, Yahoo and MSN
