Shark Week (Discovery Channel)
Age: 25 years. We’re cheating. Shark Week is an event, not a show. But Discovery’s lineup of shark-themed summer programming has been called the longest-running entertainment event on cable.
Senior Power: Discovery had record-setting Shark Weeks in recent years and the programming stunt sometimes tops the cable charts on opening night. Knock-offs have been attempted — like Nat Geo’s Big Cat Week, Discovery’s own Alaska Week — proving how uniquely successful the original is.
Survival Secret: Here’s what’s amazing about this event: There’s no cast. No regular programming or format. No specific location or set. Shark Week is just an idea. And that idea is this: SHARKS! Somehow, that’s enough.
Life Expectancy: Sharks live up to 30 years. Insiders say Shark Week might live longer.
