Update: Vudu has also launched Chromecast support.

Google already has a hit on its hands with the Chromecast, and it’s only going to get better as more apps support it. Google launched the SDK out of beta just last month, essentially giving developers the license to go wild and make their own products Chromecast-ready.

Today, Crackle and Rdio both announced support.

If you’re unfamiliar with Crackle, it’s a unit of Sony Pictures Television, and features free movies and shows, and even some originals. Crackle says:

Google Chromecast owners can now watch Crackle’s curated collection of hit movies and television shows, including genres like action, comedy, crime, horror and sci-fi; as well as original Crackle series such as Jerry Seinfeld’s Emmy nominated “Comedians in Cars Getting Coffee,” “Chosen,” starring Chad Michael Murray and Rose McGowan and “Cleaners,” starring Emmanuelle Chiriqi and David Arquette. Fan favorite shows available on Crackle include “Seinfeld,” “The Shield,” “Damages” and much more.

Crackle has apps on Android, iOS and Chrome for Windows and Macs.

Rdio is a service for listening to, discovering and sharing music. It’s available on iOS and Android.

“Rdio on Google Chromecast marks another milestone in Rdio’s commitment to delivering the best music experience everywhere,” said Rdio CEO Anthony Bay. “Music fans can access Rdio’s massive catalog of over 20 million songs or start a station easily, all from Chromecast on their TV.”

Chromecast recently expanded into the UK. Meanwhile, the competition is heating up.
