When is advertising considered to be deceptive?

 

Example 1: A consulting firm played actually a very minor role in a well-known project

Situation 1: Its brochure claims that it played a major role

Situation 2: It makes no claim but only shows the picture of the project

Situation 3: It shows the picture along with a footnote in fine print the true details about its role in the project

Situation 4: If the same statement is printed in larger type and not as footnote.

Example 2: An ad shows an electronics device to convey that the item is routinely produced and available for sale. But actually the ad shows only the prototype or mock-up and the item is just being developed.
