I'm really working my way through the classic Batman titles here! Not long after The Killing Joke, I read through a large trade paperback that collects A Death In the Family along with the follow-up-ish story A Lonely Place of Dying. The former is the more famous work, a four-issue run considered a classic for many reasons, so we'll start there.
A Death In the Family is best known for featuring the death of the second Robin, Jason Todd. He took over the mantle of Robin after Batman caught him trying to steal the tires off the Batmobile -- an origin story which I read a version of in Nightwing: Year One -- filling the role after the first Robin, Dick Grayson, left Batman's side to lead the Teen Titans and eventually take on his new persona as Nightwing.
The storyline was met with a fair amount of criticism due to an interactive aspect in its release. DC Comics allowed fans to vote on whether Robin would live or die by dialing a 900 number (this storyline was published in late 1988 and early 1989 ... so taking a vote via Twitter hashtags wasn't really an option). A total of 10,614 votes were cast, with fans voting for Todd to die by the slim margin of 5,343 to 5,271. This close margin was heavily impacted by one fan who rigged votes for Todd to die, with DC saying (over a decade later) that this one person voted enough times that he swung the vote.Read More
