Ads may not be designed to blend in with the site or mimic editorial fonts or colors. Ads may not include fake form elements or other graphic symbols that represent non-existent functionality. Frequency capping is applied to all ads that obstruct content. Examples include floating ads, user surveys, pop-up ads, and interstitials (between page ads). TI uses cookies to set frequency caps. Pop-up or free-form ads may only appear on a single page load at a time, and are subject to frequency capping. Open Window Commands: Mouse-over interaction with an ad may only invoke ad interaction within the current browser window. Simple mouse-over must not link a user to a new website. Close Buttons: All expanding ads and floating ads must include a close button. Close buttons should appear in the upper right corner of any expanding panels and include a prominent "close" or "X" designation. Floating ads must use the word "close" or a prominent "X" in close proximity to the upper right corner of the ad. Ads with close buttons that click to an advertiser website will be returned for correction.
