An article on the Seventh-Day Adventists in The Watchtower of July 15, 1997 (pages 25-29) traces that denomination's roots in the Millerite movement, but fails to admit that the Jehovah's Witness denomination shares the same roots. We reproduce here that portion of the WT article, and then supply the missing information:

from The Watchtower July 15, 1997 pp. 25-29:

THE "INVESTIGATIVE JUDGMENT"
A Bible-Based Doctrine?

OCTOBER 22, 1844, was a day of great anticipation for some 50,000 people on the East Coast of the United States. Their spiritual leader, William Miller, had said that Jesus Christ would return on that very day. The Millerites, as they were called, waited in their meeting places until darkness fell. Then the next day dawned, but the Lord had not come. Disillusioned, they returned home and thereafter recalled that day as the "Great Disappointment."
Yet, disappointment soon gave way to hope. A young woman named Ellen Harmon convinced a small band of Millerites that God had revealed in visions that their time calculation was right. She held that a momentous event had taken place on that day–Christ had then entered "the most holy place of the heavenly sanctuary."
More than a decade later, Adventist preacher James White (who had married Ellen Harmon) coined a phrase to describe the nature of Christ's work since October 1844. In the Review and Herald of January 29, 1857, White said that Jesus had begun an "investigative judgment." And this has remained a fundamental belief among some seven million who call themselves Seventh-Day Adventists.

This is what The Watchtower fails to mention:

Yet, disappointment soon gave way to hope. A small band of Millerites discovered a 30-year error in the calculations. Christ would return, not in 1844, but in 1874. The appointed date came and went, but the Lord did not come—or did He? Yes! Some of these Adventists maintained that Christ's return took place on time, only invisibly.

Nearly a decade after finding Adventism as a teenager in the late 1860s, Charles Taze Russell was serving as assistant editor of the Herald of the Morning when new light was revealed in its pages. Refusing to move ahead with the organization, he became an apostate and started his own religious magazine. But the 1874 return of Christ remained a fundamental belief of Zion's Watch Tower and Herald of Christ's Presence.

More than a decade after Russell's death his successors found a 40-year error and recalculated that Christ had been present since 1914. And this has remained a fundamental belief among some five million who call themselves Jehovah's Witnesses.

The Watchtower article goes on for pages with a tedious discussion of how leading Seventh-Day Adventist scholars are now reconsidering their belief regarding 1844. Again, no mention is made that Jehovah's Witnesses only recently dropped their prediction that the "new world" would come "before the generation that saw the events of 1914 passes away."
