SOCIAL MEDIA: JOURNALISM SPINS & ENDS

I currently travel this:

To attend my mentorship at LA Youth. Although it's quite a distance, and I absolutely loathe driving in traffic with people who don't know how to drive, I am connecting social media to journalism. I mean, to me: 

Journalism is defined as - the written expression, that may be virtual/print/digital/broadcasted/aired, to capture the spirit and pain of events, humans, and ideas. 

While, social media is defined as - the often digital, that may be video/AV/written/socialnetworks/etc, media rich interaction that combines the consumers and creators together in a virtual environment.

Despite my understanding on these definitions, I lack the breadth and depth of understanding  how a social giant becomes as big as Facebook. In future research, I plan to read and understand:
