⁵⁶. Motivated largely by huge budget deficits, Congress authorized the FCC to use an auction process for allocating PCS licenses in the 1993 Budget Reconciliation Act. This auction process replaced the earlier lottery for AMPS licenses, which resulted in widespread fraud (by promoters on an unsuspecting public) and abuse (stuffed ballot boxes). The A- and B-block auctions lasted 111 rounds and raised over $ 7 billion for the U.S. Treasury, averaging $ 15.50 per POPS; the most expensive market was Chicago at over $ 30 per POPS. The C-block auctions were held later and, despite being targeted for small businesses, raised over $ 10.2 billion.
