There are various web browser extensions that stop ads from being displayed during a browsing session. Adblock Plus is one such extensions that's actually quite popular. Ad blocking is something that irks both the ad networks as well as publishers that rely on incoming traffic to generate revenue. Google has allegedly paid Eyeo, the company that owns Adblock Plus, to not block its ads and put it on what is called the “Acceptable Ads” whitelist.
This whitelist is said to include Google as well as a number of other companies that don't want their ads to be blocked online. However these other companies have not been named yet.
