Which type of advertisement is prohibited in New Jersey?

In New Jersey, using a trademark in lieu of the company's name in advertising is prohibited because it can create confusion among consumers. The law mandates that advertisements must clearly identify the company or the provider of the service to ensure that consumers know whom they are dealing with. This transparency is crucial for consumer protection and helps maintain trust in business practices.

Using a trademark instead of the actual name may obscure the identity of the business, preventing customers from making informed decisions when engaging with the company. It's important for advertisements to be clear and straightforward, allowing customers to easily identify the provider of goods or services being promoted.

The other types of advertisements listed do not have the same regulatory restrictions; colorful graphics, lack of a contact number, or content about non-approved products are more about guidelines and best practices rather than outright prohibitions in New Jersey advertising law.
