The annual fireworks show at Channelside was underwhelming, but there's a reason.

Commenters on Twitter were quick to blame the show's organizers.

But according to Tampa Fire Rescue, which was overseeing safety at the show, a computer was to blame.

Officials said PyroTechnico, the fireworks company, was using a new program to set off the display, but it either crashed or malfunctioned. The company had to set off the fireworks by hand.

A photo tweeted by Devon Magill showed unexploded fireworks on a barge.
