Not a deal as they have always been free, as far as I am aware. Posting as some HUKD members will probably be interested.
How To Academy holds talks in London on a regular basis. Usually it is someone with a new book out. However, those who can't make it or missed attending a certain talk and have an interest of expanding their knowledge or hearing what others have to say about various topics, should enjoy these recorded videos..
Steven Pinker being interviewed by Stephen Fry
Eric Schmidt, Jonathan Rosenberg and Alan Eagle On Leadership (Google former Execs)
An evening with Russell Brand
I don't think all filmed events have been uploaded (maybe they have?) but hopefully you'll find an interest in one or more of the ones which are on YouTube. They don't film all their talks.youtube.com/cha…eos
I am not associated with How To Academy. Apart from being someone who has attended a few of their past events. Upcoming events can be found: howtoacademy.com/
The website has a few podcasts too.
