I've seen an increase of "floating" advertisements on webpages, and I must say that they are by far the most annoying yet. On ESPN, for example, I sometimes see this car moving across the screen while I'm trying to read the box scores. They usually come complete with sound effects. I must say that these are the most annoying types of ads -- worse than pop-ups -- and I would like to know what they are called and if there are any methods by which these ads can be removed?
