Welcome back to What’s NEXT, the podcast exploring the technology of the future.
This week’s episode is the third in a series of podcasts recorded during Tech Open Air 2019, where we hosted the TOA Podcast Studio to explore the human stories behind tomorrow's groundbreaking innovations.

In this episode, Jonny Tiernan of Lola Magazine talks with Chris Messina, the inventor of the hashtag, about a decade living on the edge of social technology, working with Uber and Google, and giving away many of his creations.
