Advertising

Advertising has changed greatly due to the emergence of the internet. It is costly to print paper ads with ink, it is virtually free (resources wise) to do so online. Online advertisements don't require paper and ink and in this sense resources are being saved, however it is still very costly to advertise at all. This is because the ads are often used as the sole source of revenue for many online publications, and are thus very costly. They also take up a lot of energy to run online, every hour of every day. They also require software space, they clog up the internet both in space and in visuals. Regardless of how much bandwidth is required for online advertising, these ads take up a tremendous amount of space on the screen for most publications, and it can be very irritating to have to wade through the vast amount of junk advertisements to even get to what you were searching for anyway. The reason for all of this is, as always, that it is profitable, the same reason for news publciations themselves switching to online anyway.
