2000 saw the end of "TGIF", which was struggling to find new hits (with Boy Meets World and Sabrina, the Teenage Witch, the latter of which moved to The WB in September 2000, beginning to wane as well by this point) following the loss of Family Matters and Step by Step to CBS as part of its own failed attempt at a family-oriented Friday comedy block in the 1997–98 season.
To what network did Sabrina the Teenage Witch move in 2000?
The WB
