Dear friends,
due to the Covid-19, many scientific associations recently discovered the web.
Considering that, for example:
YouTube was born in 2005
YouTube became in 2007 an independent subsidiary of Google Inc.
I am proud to remember that:
IGF videorecords all its events since 2007 and all the videos are available in the IGF YouTube channel.
IGF streamed on the FB page its first event in 2017 (IGF24 in Urbino).
IGF organized its first virtual conference in 2019 (VCSI1).
IGF is online since 2007.
