Wow, never count out a series when it comes to DVD releases. After two years of waiting, Season 2 of Happy Days will be released in April 2007.
Those who remember my posts from way back in 2004, when the first season was released, will remember that I'm a big fan of the early Happy Days, when it was filmed with no studio audience and Richie was the lead character. The second season was the last one filmed that way. There's actually one episode where they experimented with the live-audience, three-camera format ("Fonzie's Getting Married"). It was one of the weakest episodes of that season, so naturally they switched full-time to that format starting with the third season, and Happy Days became more successful, more popular, and much, much less good.
