Say good-bye, Goodyear blimp. Your ride is now obsolete. Lightship unveiled this beast of a blimp at the NAB broadcast conference last week. It has a massive 30-foot by 70-foot LED screen that displays over 30,000 pixels. During the day the screen is limited to a single color for visibility reasons, but at night anything goes. The airship has already been FAA approved but marketing demand is still being researched so it may be a while before it appears at any sporting events.
