For the last 18 years Tech Radio has featured guests ranging from the brains behind multinational brands to researchers working on emerging technologies to start-up entrepreneurs, to young people with big ideas.

This week Niall, Dusty and some friends of the show look back on 1,000 episodes with some friends of the show.

Sharing their opinions on travel, money, transport and tech's most influential personalities are roundtable veterans Jason Walsh and Martha Rotter. We also have contributions from Ai Institute founder Maryrose Lyons; Back From The Future boss and gadget guru Colin Baker; cybersecurity expert and BH Consulting CEO Brian Honan; and Fujitsu Ireland distinguished engineer Caragh O'Carroll.
