This would require an very long answer, but the short version is we only concentrate on Sanger sequencing. It is an open secret that Sanger sequencing never went away. The large genome centers sold off all their sequencers and they were bought by small facilities and companies around the world. These are all still being used.<p>Sanger sequencing is far from dead as none of the NGS sequencers are as good at what Sanger sequencing excels at which is sequencing short sections of DNA. This demand is still there.
