Broadcasting the Blogosphere: 30 million voices for the price of one!

March 13, 2006 in Applications, Services, public broadcasting by Administrator | 2 comments

What is the size of the whole blogosphere? What capacity would be required to transmit it over a broadcast channel? Let’s see…
 
Blogging is still exploding. In his “state of the blogosphere” speech last week at ETECH, David Sifry, CEO of the blog indexing web service Technorati, presented the latest statistics:
  • 30.000.000 blogs worldwide
  • 100.000 new blogs are created daily
  • the blogosphere is 60 times larger than 3 years ago
  • there are 1.5 million legitimate posts(by humans for humans) per day

Let’s assume that each post contains 500 characters, no pictures, and that they are posted regularly over time. This would produce a constant bandwidth of:

500ch * 1byte/ch *1.5 million = 750 Mbytes / day

or

70 kbps !

What? The most massive conversation of the world requires only 70 kbps? That’s less than a single digital broadcasting audio channel! That’s 30 million voices for the price of one! Let’s turn the numbers around once again: with 70 kbps we could have each and every Canadian (30 million, all ages!) broadcast one 500 characters message to all other Canadians every 20 days?!?

That’s impressive. Does that make sense? I think I would agree to trade a local FM station in my area for this new “Whole Blogosphere Channel”. Would you?
