No, I don't think "Mr. Kissy Kissy" as my grandma used to call him, would offer a kiss to each lady who'd appear on the show today (nor have the nearly 1/2 dozen guys who've hosted Family Feud since Dawson's time. Indeed, I can't imagine the guy from the TV show "Tool Time" who later hosted Family Feud going in for a smooch from each female contestant.)
That said, there are a number of things that were somewhat regularly seen on game shows and talk shows that one would never see today. Charles Nelson Reilly smoking his pipe on Match Game, Carson and his guests lighting and smoking cigarettes while chatting away (at least one of Carson's earlier desks had a built-in holder for this ash tray). Many of the more un-PC guests on Carson's show who seemed funny then, wouldn't fly today (I remember Don Rickles trying to speak jive to a black member of the crew, and a lot of Buddy Hackett's material may not work today). I also remember a LOT of double entendres and more adult-themed humor on game shows back then..Everything from Match Game to Hollywood Squares to the Gong Show. I recall one time when they asked one of the famous actors on one of the game shows to demonstrate the breast stroke. I'm not sure what her had was doing, but they blacked it out from view of the camera, and it certainly wasn't the swimming technique. Chatter on Carson could be racy, as could some of his sketch comedy, especially the ones with the supporting cast of large-busted women in short skirts and heels.
Cut to more recent times, I recall on one of the last telethons Jerry Lewis hosted, he started joking with a member of the staff, and made reference to him using a homosexual slur that's 3 letters long, starts with f and ends in g (I initially spelled the word, but it was blocked here). This was probably in about 2009. I remember the backlash in the media and on talk radio was swift and brutal.
