From the FIDE web-page for the "laws of chess":

"9.3  The game is drawn, upon a correct claim by the player having the move, if
he writes on his scoresheet, and declares to the arbiter his intention to make a
move which shall result in the last 50 moves having been made by each player
without the movement of any pawn and without the capture of any piece, or the
last 50 consecutive moves have been made by each player without the movement of
any pawn and without the capture of any piece."

This decision was made by the group that administers the rules of chess, FIDE,
because there were getting to be so many "exceptions" to the 50 move "rule" that
it was hardly a rule anymore.  Even a "200 move rule" would not fix the problem
in some extreme and rare cases.  Since the rules of chess are designed for
humans, and most humans don't want to play out a 200+ move endgame, the 50 move
rule reverted back to the way it was.  Actually not quite back to the way it
was.  For many, many decades there was a 50 move rule exception for KNN vs KP,
which had long been known to have possible wins that take more than 50 moves.  I
believe that today even this long time exception is gone.
