I would guess the Minnesota Vikings for the NFL since they have been in the league since 1962 and never won it all (unless you count the 1969 NFL championship they won before losing to KC in SB IV).  The Cardinals won it all in 1947, and the Seahawks were est. in 1976.  The Astros/ Colt 45's have been in MLB since 1962 and have never won the WS.

Man, and all along I thought you were a trivia expert, creating these questions for our enjoyment!

The Cubbies or Red Sox aren't in there somewhere?

[KnightsRule]

I would say Chicago Cubs is definately longest in baseball and probably longest in 4 major sports with white sox and red sox on their heels.  Cubs last won world series in 1908, white sox 1917, red sox 1918.

Question was "without a championship" though, not the longest drought.

This site has sections for each major sport, with a "Streak without a championship" section for each.

The Texas Rangers have gone 43 years of existence without winning a championship.  The Astros are right behind them at 41 years.

The Minnesota Vikings have never won a championship in 42 years of existence.  They're the longest in the NFL.

NBA?  The Denver Nuggets, the Indiana Pacers, and New Jersey Nets have all never won a championship in their existence (36 years), the longest in the NBA.

Hockey?  The LA Kings and St. Louis Blues have gone 37 years of existence without a championship.

And, just FYI, the longest streaks since last winning a championship:

MLB:  Chicago Cubs (95 years)

NFL:  Arizona Cardinals (56 years)

NHL:  Chicago Blackhawks (43 years)

NBA:  Sacramento Kings (52 years)
