One of the questions I frequently receive goes something like…

“Web2.0 sounds great. But are there any web2.0 companies that have been successful [or profitable]?”

One of my favorite blogs, Rev2, has put together a list of the ten “most successful” (always a relative term, of course) web2.0 properties based on stats like these…

(1) MySpace                                            

Launched: July 2003
Founded by: Tom Anderson and ,Chris DeWolfe
Type: Social Network
Targeted Audience: 16 – 24 (teens, young adults)
Approximate Users: 150 million (100 million as of August 2006; growing at around 200,000 registrations per day)
Approximate Pageviews: 40 billion per month (as of March 2007)
Acquisition/Valuation: Bought by Rupert Murdoch’s Fox Interactive Media in July 2005 for $580 million

Of course, MySpace is number one, but a few others include Facebook, YouTube, Flickr, del.icio.us, Netvibes and (my personal favorite because I use it so much) Meebo.
