Mad Men is one of my favorite TV shows. Each episode generates a lot of internet analysis, and my go-to blog for Mad Men is Tom+Lorenzo, aka “TLo”. They have insightful posts on each episode, and even better yet a great crew of readers who leave hundreds of comments. Mad Men has an ensemble cast where a character will figure prominently in one episode and not even show up in the next. One possible way to show how characters come and go is to count how often each character’s name shows up in the comments. So I quickly scraped TLo’s blog, and created this graphic. See my website for the code and methodology.
