This text based ad launched in conjunction with the 2015 Superbowl (New England Patriots vs. Seattle Seahawks). The ad makes use of color and contrast (using a dark font on a light background) while using an all caps, sans serif, slab font. There is no header or subheader, and the all the type functions as body text.
This text based ad is promoting the Mars Candy bar. I find this ad confusing and not very effective because I don't know how the phrase "1 New message" is supposed to relate to a Mars bar (which is similar to a 3 Musketeers bar). This ad uses a sans serif, italicized, slab typeface in a bold red color. The main phrase "1 new message" is treated as the most important text in the hierarchy (as a header) while the sub header catch phrase is listed by the logo. To help distinguish the sub header, it is shown in a different color and regular (not italicized).
This text based ad utilizes a script, serif font. The main text is the first thing that you see on the page, due to its size and the contrast that it has against the background. The wording that the ad is using is also very complimentary to the product itself (dark chocolate) as it is appealing to the sensual and delicious senses.
This interesting ad (from the recent Left Twix vs Right Twix campaign) uses a sans serif, slab font in contrasting colors. The first thing the viewer notices is the header and the variation of the popular colloquial way to pronounce the word caramel. The font is stylized to appear "ballooned" and has spots to help visual interest. The Twix pieces also help the balance of the ad by using leading lines to direct the viewers eyes directly to the header text.
This colorful ad uses a strong decorative , sans serif font to feature Tropical Starburst. The text itself appears in a droplet that descends from the Starburst package (subliminal messaging to Starburst being juicy) and is formed in a body text pattern. There is subtle size differences between the lines of text, attributing to the flow down the ad, but there's not enough to distinguish a clear header or sub header. In fact, the size differences seem to highlight irrelevant words in the body text (THE LOUD, WILL BRING) and appears to be only used for placement convenience instead of the more descriptive (TROPICAL, TASTE WILL)
