What is a 160×600?
The 160×600 ad size is generally placed on the side of a page, so as to show users an ad as they scroll down the page. This makes skyscrapers (of both types) somewhat immune to demands for above the fold placements.
The 160×600 was brought in to replace the old 120×600 skyscraper ad unit because of it’s consistently better performance (due to being very large compared with the 120×600). The 120×600 however still remains somewhat frequently in use so should not be ignored. The 160×600 is still more commonly served through a multi-size ad slot with a 120×600 ad unit, so that either ad size can appear in the same ad slot.
This is how it looks:

You can generally expect a reasonable CPM for this ad unit, however it will often be lower than the 728×90 or 300×250.
If placed aligned with a 300×250 along the right side of a webpage, this ad unit can make up part of a homepage takeover.
This ad slot is often difficult to fill (whether using a 120×600 or 160×600) due to lack of demand, so having both options available is the best choice.
