Answer:
1. an advertising technique that uses a new kind of technology to communicate its message
Mobile video advertising
Mobile video consumption is growing rapidly and providing advertisers with a way to reach consumers when they are paying attention. Between Q3 2012 and Q3 2014, smartphone and tablet video consumption grew 400 percent and now accounts for 30 percent of all online videos played, according to Ooyala’s Global Video Index. This trend has been helped along by the expansion of fast 4G/LTE coverage. The bigger iPhone 6 screen and the popularity of other ‘phablets’ (large-screen smartphones) also reflect the growing importance of mobile video. As phablets saturate the market, they will in turn feed the growth of mobile video.
2. an advertising technique that is most effective at the point of sale (i.e. at the moment the customer purchases the product)
The display of candy bars within immediate reach reminds you that you’re a little hungry, so you grab one (it’s on sale). Oh, and that magazine looks interesting. You’re already reading an article when you get to the cash register, where the teller asks if you want to donate $1 to a charity; and doing so, you write your name on a little heart placard that gets placed on the wall with a hundred other hearts from other donators. Finally, you complete your purchase(s) and get your receipt—with several extra items you hadn't expected to buy.
Point of sale marketing refers to all efforts that increase sales at the point the purchase is actually made. Primarily this revolves around a cash register (although a point of purchase for a business might be a meeting table, or an Internet page), and is a staple of retail and restaurant environments
3. a real-world case study of a company that was legally penalized for making false advertising claims
On March 29, 2016, the Federal Trade Commission (FTC) filed a lawsuit against Volkswagen, which claimed that the car company had deceived customers with the advertising campaign it used to promote its supposedly "Clean Diesel" vehicles, according to a press release.
In 2015, it was exposed that VW had been cheating emissions tests on its diesel cars in the US for the past seven years.
The FTC alleged that "Volkswagen deceived consumers by selling or leasing more than 550,000 diesel cars based on false claims that the cars were low-emission, environmentally friendly."
