Just like TV was different from Radio, the Internet is different than TV. Traditional TV had/has "gate keepers" to filter the raw information and present it with a certain level of professionalism. With the Internet, these gate keepers are less important/powerful/needed. Individuals can "create" their own information feed based on their own pre-chosen resources (legitimate or not).

Yes, cable TV expanded TV beyond the "big networks" (CBS/NBC/ABC etc.) but the democratization of news, reporting and information spreading is entirely new.
