Goodyear Blimp
Goodyear's first blimp, Pilgrim, took off on June 3, 1925, and the company has flown airships for the century since. That makes its fleet the longest-running story on this list.
The blimps gave television its aerial view of big events, with a live broadcast of the Rose Parade and Rose Bowl Game in 1955 and Super Bowl I for CBS in 1967. Today's Wingfoot ships are technically semi-rigid Zeppelin NTs rather than true blimps, but they still float on helium and the old name has stuck.
