Final answer:
The National Do Not Call Registry significantly decreases telemarketing to individual consumers, though not affecting nonprofit or existing business relationship calls. Advancements have led to increased consumer choice and cheaper, better-quality phone service.
Step-by-step explanation:
The National Do Not Call Registry has largely reduced telemarketing to individual consumers. This federal initiative was designed to limit the number of unsolicited marketing calls individuals receive. The registry does not restrict calls from all organizations, such as charities, political calls, or calls from companies with which individuals already have a business relationship, but it does significantly reduce cold calls from telemarketers. Furthermore, developments in technology and changes in regulations have increased consumer choice, promoting cheaper phone calls and better-quality phone service, which allows for alternative methods of communication beyond the traditional landline telemarketing calls.
