The Mac and iPhone developer that's been running the tr.im URL-shortening service called it quits Sunday, saying it was shutting down the service after it failed to find a buyer.

Nambu Network, a small British Columbia-based developer, has also stopped development of its Twitter and FriendFeed clients for Mac OS X and the iPhone.

"We're accepting the realities and moving on," said Eric Woodward, the president of Nambu, in an interview late Sunday night.

Tr.im, which competed with other services such as bit.ly and tiny.url, converted conventional URLs into shortened strings that redirected users to the original destination. The services are accessed by Twitter users to add links to their tweets, which are limited to 140 characters.

As of Sunday, tr.im is not accepting any new URL shortening requests. "Tr.im is now in the process of discontinuing service, effective immediately," a message on tr.im reads.
