I saw a program on TV last week called "Dancing With The Stars".  This was new for me.  When did this show hit the airwaves?
I am not sure when it started but it was around in 2006 and 2007 as it was the most popular in the world. 
I must have been hiding in my cave.  What is the purpose of this show, and why do they pair up with celebrities?
The celebrities are on a team with professional ballroom dancers and compete each week. 
Is Ballroom Dancing really a thing in the age of rap music and thug life and meme culture?  Are you sure this is a really popular show or are you pulling my leg?
It is very real, and the viewers get to vote for their favorite by the phone or online. 
Oh, i must have missed that part of the show, i was baking a cake at the time; i love baking.  So once tthe audience votes, do they kick a team off or do they go to a dance off round?
The audience and the judges vote and then the team  with the lowest score is no longer on the show. 
So the last show of the season is the two teams that are remaining?  Which celebrity has won this in the past?  i just need one name.
Yes at the last show, there are two or three teams left and one wins out of them. I am terrible with names and can't recall a winner.
Well, you have really made me want to watch this show in the future.  Now that i know what is going on, i am sure i will enjoy it.  Thanks for your time and all of the information.
