After five years of delivering “ideas worth spreading” to sold-out audiences of Bendites, TEDxBend needed to expand. In fact, it needed to double.

This year’s sixth annual TEDxBend event, the local version of the celebrated TED conferences that started in 1984 and became an annual event in 1990, will feature a morning session from 8:30 a.m. to 12:45 p.m. and an afternoon session from 2:15 to 6:30 p.m. In past years, the event took place between 1 and 6 p.m. and featured eight to 11 speakers and performers; this year, the event includes 17 speakers and four performers.

“One of the challenges that TEDxBend has faced is that the event has sold out every year. It used to be at Summit High School, which is a much smaller venue, and we moved it to Bend (Senior) High (School) three years ago,” said lead organizer Moe Carrick. “… Last year, we did a ticket lottery to try to get a feel for just how big is the audience, and we did sell the lottery out. So we’ve consistently gotten feedback that says, ‘I can’t get a ticket, I’m so frustrated.’”

TED (Technology, Entertainment, Design) events are centered around TED Talks, which are no more than 18 minutes and cover a wide array of topics in science and culture. The main conference is held annually in Vancouver, British Columbia, Canada.

Past TED Talks are available to stream online at ted.com, and many have gone viral. One of the requirements to hold a TEDx event is for all talks and performances to be professionally recorded, Carrick said. Two Bend TED Talks have been picked up by ted.com: Molly Winter’s “The Taboo Secret to Better Health” from 2016, and Emilie Wapnick’s “Why Some of Us Don’t Have One True Calling” from 2015.

TEDxBend’s theme this year is “Us Humans.” The theme is related to the national TED theme, which this year is “The Future You.”

“Part of that is, given the very dynamic global and domestic political environment today, we felt like focusing on the future you would not be complete unless we really focused on the future us — how is it we’d be together in community here in Central Oregon,” Carrick said.

In addition to the two sessions, TEDxBend will introduce TEDxBend Fest, which will take place at the high school from 12:30 to 2:30 p.m. and feature outdoor performances from local groups Mosley Wotta and Ubuntu, as well as free food from local food carts. TEDxBend Fest replaces the after-event bash from past years.

In addition to this main event, TEDxBend also hosts two TEDxBend Women events every year (the next one is from 9 a.m. to 2 p.m. Oct. 29 at Central Oregon Community College’s Redmond Technology Education Center), as well as monthly salon events hosted in various locations around town that feature previously recorded TED Talks.
