The first Golden Collection was released way back on October 28, 2003. For awhile it seemed like Warner Home Video had no idea how to handle releasing the Looney Tunes onto DVD. There were doubts that a 4-disc set aimed at collectors would even sell at all. Luckily, folks like George Feltenstein and Jerry Beck were put in charge and made the first Golden Collection a huge success.
Let's take a look at the original trailer WB Home Video put together to promote this first release. You do get the impression that they still didn't know who they were marketing this set for (note the mention of "Games and Much More!" among the extras on the DVD... seriously.)
