1G was typically scrapped when they went to 2G. 1G for most was Analog cellular (AMPS). Since digital technologies made spectrum much more efficient, they were able to chop out some channels to deploy simultaneous 1 and 2G. They then phased out analog eventually replacing it with digital of some sort either TDMA or GSM initially. Some waited long enough to go to IS-95 CDMA skipping the TDMA phase and later auction winners (post 96) started with either IS-95 or GSM. I was involved in a lot of that back in the day.
