Google is presenting the first-ever Google TV Hackathon Weekend for television-loving Android geeks later this month.

The Internet giant announced today that it is collaborating with the Silicon Valley Android Developers Group and the London Android Group to host two simultaneous TV Hackathons with the goal of creating new experiences for Google TV.

The SVAndroid Hackathon is taking place at Google TV headquarters in Mountain View, Calif., and tickets are $20, but purchasing options end April 17.

Team ideas will be announced April 20, and the following day is “devoted to building, with breaks for demo sessions, Q&As, and a hangout with Google TV developers,” according to the Official Google TV Blog. The teams will present ideas to judges April 22 for the chance to win tickets to Google I/O and other prizes.

The Londroid Hackathon is occurring at the Google Campus in London, United Kingdom. It will run concurrent with the Mountain View event to gather Android devs throughout Europe.

“We will kick things off bright and early on Saturday, April 21, with introductions and background information on developing for Google TV. Teams will power on through Saturday night so that we can do a round of presentations and prizes at lunchtime on Sunday,” explained Google TV Senior Developer Advocate Paul Carff on the Official Google TV Blog.

In related news, Google TV announced through Google+ today that it is holding a Hangout at 11 a.m. April 10 with Google TV product managers:

“Send us your questions ahead of time. And if you can’t make the live event we will have a recording available,” Google TV explained.
