Pop-up front/ under ads
They are useful because everyone will see them because they go over what they are trying to view on the page but people can get annoyed with pop-ups easily.

They are useful because they have an interactive feature to them which can cause enjoyment but they can also cause the page to load slower because they take up a larger file
They are useful because they are moving which will catch someone's eye quicker than a stationary picture but if they move too fast then they may not be seen by the person visiting the site
Rich media ads
They can be bad because the user may need a higher speed internet service or the page will not load properly but it helps to attract attention to the ad and can cause people to click on and visit the ad more often.
Can be slow if person does not have a high speed internet connection. Useful because it can help bring people to a certain game site or another site if they get into the game ad that they are playing.
