Timeline over the past 25 years -
May 1990 - Barney Bellomo made acting boss after Vincent Gigante is indicted in the Widows case.
June 1996 - Barney Bellomo indicted. Dominick Cirillo becomes acting boss. Also establishes a ruling panel.
May 1998 - Dominick Cirillo steps down after a heart attack. Frank Serpico follows as acting boss but steps down some time between then and April 2001 when he's indicted as the "former acting boss." Whenever that was, apparently Ernie Muscarella followed as acting boss.
January 2002 - Ernie Muscarella indicted as acting boss.
Artie Nigro was reported to be acting boss in November 2003 so he probably succeeded Muscarella.
If what former FBI agent Jaoquin Garcia said was correct, Pasquale DeLuca was probably acting boss at some point during this time, since it would fall within the December 2002 - March 2005 time frame of Garcia's undercover work; though it's not clear for how long since we don't know exactly when Dominick Cirillo resumed his the role after he recovered.
April 2005 - Dominick Cirillo indicted as acting boss.
July 2005 - Matthew Ianniello indicted as "an" acting boss, as opposed to "the" acting boss. This is wording is probably intentional by the feds, which suggests he was on the ruling panel.
December 2006 - Danny Leo identified as acting boss (from his previous position on the ruling panel) and indicted as such in May 2007.
June 2009 - NY Daily News article identifies Benny Mangano, Ernie Muscarella, Barney Bellomo, and Larry Dentico on a "rotating panel" of recently released senior members running the family.
September 2009 - NY Times article identifies Tino Fiumara as being on a "three man panel" running the family. This is reported against in 2011 after his death.
February 2010 - Artie Nigro indicted as the "former" acting boss.
February 2014 - Wall Street Journal reports Genovese family likely still uses a rotating panel of leaders to run day-to-day affairs to avoid any one boss from being targeted by prosecutors.
