Turner Broadcasting admits it was a promotion for Adult Swim's Aqua Teen Hunger Force cartoon.
"WBZ) BOSTON The suspicious devices which forced bomb units to scramble across Boston today were actually magnetic lights that are part of a marketing campaign for a television cartoon.
The reports forced the temporary shutdowns of Interstate 93 out of the city, a key inbound roadway, a bridge between Boston and Cambridge, and a portion of the Charles River but were quickly determined not to be explosive.
"It's a hoax -- and it's not funny," Gov. Deval Patrick said.
All of the devices are magnetic lights which resemble a character on the show "Aqua Teen Hunger Force", on Turner Broadcasting's Cartoon Network.
A total of ten devices were found in Boston, Cambridge and Somerville.
The first device was found at an MBTA subway and bus station located under Interstate 93 on Wednesday morning. The device was detonated and determined to be harmless, but as a precaution the station and the interstate shut down temporarily."

After seeing the video; It's a LiteBrite with a magnet.
Nothing to see here, folks, move along. It's called art. There's no need to call out the bomb squad and shut down the city of Boston for a few LED's. Paranoia has reached new levels.
