History of sit-n-go tournaments?

[ds914]

Does anybody know a good resource that details the birth and growth of single-table tournaments? I've found that Eric Drache is often credited with creating satellite tournaments during the early years of the World Series of Poker, and I wonder if this would be considered the official "creation" of sit-n-go tournaments.

Did online poker rooms really shape and perfect the set-up? Which was the first room to offer them?

Any and all help will be most appreciated.

Thanks...
