I was able to elicit from Sri. Lalitharam some statistics about the Parivadini YouTube uploads. Apparently, this is not a complete list as videos have been uploaded under two different names.
The Parivadini Channel from Dec.1, 2014 till Sep.3, 2017:
1. 500 live concert uploads of average duration exceeding 2 hours! So a minimum of 1000+hours of Carnatic concert music, live video
2. Over 629000 views!
3. Over 104 thousand hours of viewing!
Hats off to Parivadini. With minimal marketing, almost zero funding, an idea has taken firm roots, to spread Carnatic music digitally around the world. Blessed are the artistes, organisers and the listeners.
I thank Sri. Lalitharam and Parivadini heartily for this yeoman service.
