During the first web boom many businesses were based on eyeballs more than actually building real value. Many ads were typically quite irrelevant and web users learned to ignore the most common ad types.

In many ways text ads are successful because they are more relevant and look more like content, but with the recent surge in the popularity of text ads some have speculated that in time people may eventually become text ad blind as well.

Nick Denton stated:

Imagine a web in which Google and Overture text ads are everywhere . Not only beside search results, but next to every article and weblog post. Ubiquity breeds contempt. Text ads, coupled with content targeting, are more effective than graphic ads for many advertisers; but they too, like banners, will suffer reader burnout.

Ad targeting based on past recent experience and/or implied intent. For example, if I recently searched for mortgages then am later reading a book review the page may still show me mortgage ads.
