New series in bold.

Fall 1998

Note: CBS replaced Tales from the Cryptkeeper with Mythic Warriors on November 7, 1998. Note: Fox originally intended to air a series based on Captain America at 10:30 AM, but Marvel Comics' then-recent bankruptcy caused the series to be cancelled in pre-production; hence, The Secret Files of the Spy Dogs was moved there from its original intended position on weekdays.
