Yep, RunningMan is right, the Society no longer link the 'generation' to 1914.

We do not need to know the exact timing of events. Rather, our focus must be on being watchful, cultivating strong faith, and keeping busy in Jehovah’s service—not on calculating a date.Eager to see the end of this evil system, Jehovah’s people have at times speculated about the time when the “great tribulation” would break out, even tying this to calculations of what is the lifetime of a generation since 1914. However, we “bring a heart of wisdom in,” not by speculating about how many years or days make up a generation, but by thinking about how we “count our days” in bringing joyful praise to Jehovah. (Psalm 90:12) Rather than provide a rule for measuring time, the term “generation” as used by Jesus refers principally to contemporary people of a certain historical period, with their identifying characteristics.

8 Yes, the complete triumph of the Messianic Kingdom is at hand! Is anything to be gained, then, by looking for dates or by speculating about the literal lifetime of a “generation”? Far from it!
Therefore, in the final fulfillment of Jesus’ prophecy today, “this generation” apparently refers to the peoples of earth who see the sign of Christ’s presence but fail to mend their ways.

15 Does our more precise viewpoint on “this generation” mean that Armageddon is further away than we had thought? Not at all! Though we at no time have known the “day and hour,” Jehovah God has always known it, and he does not change. (Malachi 3:6) Obviously, the world is sinking further and further toward terminal ruination. The need to keep awake is more critical than it has ever been. Jehovah has revealed to us “the things that must shortly take place,” and we should respond with an absorbing sense of urgency.
