Timeline — what shaped the curve

12007-01SRA launched — NCBI established the Sequence Read Archive in 2007 as the first public repository for raw next-generation sequencing reads, the foundation later mirrored by ENA/EBI.
22007-01Illumina NGS arrives — Solexa's Genome Analyzer (acquired by Illumina in 2007) brought gigabase-scale short-read sequencing to market, triggering the explosive growth in submitted read data.
32008-011000 Genomes Project — Launched in January 2008, this international effort to catalogue human variation drove a large early wave of high-coverage read submissions to public archives.
42015-05Nanopore MinION — Oxford Nanopore's portable MinION became commercially available in May 2015, adding real-time long-read sequencing to the data deposited in ENA/SRA.
52020-01-10SARS-CoV-2 genome — The first SARS-CoV-2 genome (Wuhan-Hu-1) was shared publicly on 10-11 January 2020, kicking off the largest pathogen-sequencing surge ever recorded in the archives.

Each record is one submitted sequencing run. Cumulative; only goes up.
