Final answer:
The Sears ad that popped up while Kaitlyn was on another website is an example of a pop-up advertisement, aimed at capturing a user's attention through interruption.
Step-by-step explanation:
The Sears ad that appeared while Kaitlyn was waiting for the Tommy Hilfiger apparel site to download is an example of a pop-up. This type of online advertisement opens in a new browser window or tab, and it often does so while a user is viewing different content. These ads attempt to capture a user's attention by interrupting their current activity, in this case, browsing another apparel site. There is a broad array of online advertising strategies that businesses leverage in the attention economy, which Naomi Klein discussed from an antiglobalization perspective in No Logo. The goal is to expose consumers to the same brand message across various platforms, as seen in the seamless integration of Miller beer ads within a sports stadium context.
