This week tech blog TechCrunch hosted the third iteration of its annual start-up show in San Francisco, the TechCrunch50, where
50 new sites and services were launched.
The show was
started in early-2007 by TechCrunch founder Michael Arrington and
entrepreneur and Weblogs co-founder Jason Calacanis as an
alternative to the DEMO conference series.
Instead of paying to be on stage (once selected) as is done at DEMO,
companies selected by Arrington and Calacanis get to present for free.
Here are some highlights of the show, in pictures.
