YouTube has reached a couple of milestones recently, including:

• more than 24 hours of video uploaded per minute
• over two billion video views per day (see the Mashable post)

YouTube also turned five years old a couple of weeks ago, and here is a video which celebrates its remarkable short history and growth.

Twitter Feasibilty Study Excerpt (2006) from 747 Media on Vimeo.

When did you first hear of Twitter? Four years ago, could people have predicted the evolution of this micro-blogging site at its onset?

Apparently, yes.

The 20-somethings that were interviewed as part of a study by 747 Media were able to assess the power of Twitter quite accurately, even though they had never used it. In this video, you will see them react to the information they’re given and talk through several of the applications that have made Twitter into what it is today.
