If you are trying to get tickets, go directly to TicketWeb as the Paley Center site is not handling the influx of hits. Passes, packages, and the Swingtown event are sold out, but it looks like there are still tickets for all of the other shows as of right now.
The 26th Annual William S. Paley Television Festival is coming to the Cinerama Dome at Arclight Hollywood April 10-24, 2009. Paley Fest is an event that celebrates current, past, and even future TV shows. Attendees are treated to an episode and/or clips viewing followed by a panel discussion with cast members and the creative forces behind their favorite programs. There are opportunities for the audience to ask questions and on certain nights even get autographs and photos with willing guests of honor.
Ticket packages and a premium pass are already on sale. Tomorrow morning, Thursday February 26th, individual tickets go on sale to members of the Paley Center for Media at 9am PT. Popular shows do often sell out to members. Otherwise, tickets go on sale to the general public on Sunday, March 1st at 9am PT.
