Medium Rectangle (mrec)

Mrecs are the most common advertising seen on web sites. They are 300px wide by 250px high and can be placed in content (within a story) or in sidebars or footers. They can be simple jpg or png files or animated gifs.

Those are Mrec you see right there in the sidebar! —>>>>

An inline Mrec can run between, above or below story posts.

Sidebar positioning is very popular because it’s seen at every page load.

They can also be placed below other sidebar content if desired – as seen below.
