In 2005 Google initiated a speaker series that has only grown in popularity. It’s best summarized on their YouTube channel: “The @Google Talks program brings authors, musicians, innovators, and speakers of all stripes to Google for talks centering on their recently published books and capturing the popular and intellectual zeitgeist of the day.”
Most recently Tina Fey came to participate in one of these Google Talks in the midst of promoting her new book, Bossypants. They’ve also recorded and posted interviews with people like Lady Gaga, Rainn Wilson, Condoleezza Rice, Molly Ringwald and Rick Steves. There are also musical performances included by bands like Mumford and Sons and Jimmy Buffett.
You should definitely check out @GoogleTalks – they’ve been going on since 2005 so there are plenty of interviews to keep yourself entertained. (The Talks were discussed in an article in the 5/12/2011 edition of The New York Times – here’s the link if you’re interested).
