On Tuesday, the first installment of the "Dr. Horrible Sing-Along Blog" was posted online, but the demand to see the musical was so great that the site crashed. The musical is the brainchild of Joss Whedon, better known for being the mastermind behind other successful shows such as "Buffy, the Vampire Slayer", "Dollhouse" and "Firefly". The other two installments will be released tomorrow, the 17th of July, and Saturday, the 19th of July.

Maurissa Tancharoen, co-creator and writer of the musical estimated that about 200,000 people visited the site every hour and since no one thought so many people would want to see it, it was believed that the servers could handle the traffic, but there was so much of it that they eventually crashed. The problem was quickly remedied so that fans all over the world could watch the musical. Hopefully this sort of incident will not happen again when the other two installments are released.

The musical's creative team issued this statement: "We love you for crashing the site, we really do. In the meantime, those of you who have iTunes capabilities can go there and get your fix. Our site should be up and running again in a few hours. Your support is warming our hearts […]. So thank you thank you."

The musical presents the struggles of Dr. Horrible as he battles his archnemesis Captain Hammer, tries to woo his neighbor Penny and strives to become a better villain so that the Evil League of Evil will welcome him. The creative team of the musical came up with the idea for it earlier this year, during the much talked about writers' strike. The "Dr. Horrible" creative team is made up of Maurissa Tancharoen, Joss Whedon, Jed Whedon, and Nathan Fillion.

"The idea was to make it on the fly, on the cheap - but to make it. To turn out a really thrilling, professionalish piece of entertainment specifically for the internet. To show how much could be done with very little. To show the world there is another way. To give the public something for all your support and patience. And to make a lot of silly jokes. Actually, that sentence probably should have come first," says Josh Whedon.
