As entertaining as I find everyone's theory about the disclaimers, and as much as I support cynical Elmo-era bashing, I do think that people's responses to this have made it a much bigger deal than it is. The show's purpose has always been to reflect the popular aspects of television/pop culture and use them to engage and teach young viewers. The world changes, television changes, Sesame Street changes. Whether we like it or not, the Sesame Street that preschoolers watch today is not the same as the Sesame Street from other eras that we celebrate, and the disclaimer may therefore be deemed necessary by either the legal or marketing folks at Sesame Workshop. Also, remember that Bob's wording on the first volume of DVDs was simply that the shows "may not meet the needs of today's preschoolers". The commentary and hysteria that has ensued would lead some to believe that the wording (or the intention) was much stronger than this.
