The first episodic content, Half-Life 2: Episode One, from Valve, has gone gold and should be available on June 1st.

Episode One is set for release June 1st via Steam and at retail outlets around the world. As we approach the launch of our first episodic release, we will be releasing a series of short gameplay clips that will focus, like Episode One, on Alyx. You will find these shorts in the new My Media area of Steam.
