The event was part of the Fraser of Allander lecture series, a three-way partnership between The Herald, Strathclyde University, and the International Network of Street Papers.
Mr Snow is an ambassador for the INSP, which represents 120 street papers worldwide, including the Big Issue.
The second conversation in the series will be between Alistair Darling, leader of the Better Together campaign, and Herald and Sunday Herald writer Alan Taylor on December 6. To book, visit the university's online shop at onlineshop.strath.ac.uk
