I'm a very nostalgic person who likes the shows I grew up with. Any chance to watch those shows with the original commercials is a huge bonus to me. It's an even bigger bonus if the PSA (public service announcements) and other announcements are of the local variety. For example there was a commercial that ran in the 60's for a bank and it simply said, "Oak Park Federal scoreboard Cubs 3 Giants 2." Since I live in Chicago that has more meaning to me.
What's odd for me is that I don't know anyone on a personal level who likes this stuff. I dragged my wife to Chicago's Museum of Broadcast Communication a few years ago to see some tapes of Bozo's Circus and Ray Rayner & Friends which was a popular afternoon and morning kids show on WGN back then. These shows had the vintage commercials in place just as they were on the day they were broadcast. After a few minutes I could tell that she was bored. I've also shown stuff to co-workers and friends but I neve get the same level of enthusiasm that I have for them. I guess I imagined that most people would like to see the stuff they grew up with in the same format they first saw it in but I guess not.
