September 30, 1986
This report provides background and analysis of the general revenue sharing program (GRS) as authorized in the State and Local Fiscal Assistance Act of 1972 (P.L. 92-512, the 1972 Act). The GRS program was extended three times before finally expiring on September 30, 1986.
So, it lasted 14 years ('72 to '86).
The money went to states and local govs.
The 1st year it had $30.2B authorized. Since then we had the OPEC inflation of the 70s, so I would suggest $300B to $500B a year now. I'm no expert and this is just my guess to get us in the ballpark.
