Instagram is a photo and video sharing social network founded in 2010, and acquired by Facebook in 2012. Why am I telling you this?
Well, within 10 years of it's founding, Instagram became possibly the most widely used place to publish glamour shots of Warhammer 40,000 and [[Age of Sigmar] miniatures. It supplanted the older web forums, like DakkaDakka and CoolMiniOrNot, that had been around in the decade prior. It also supplanted Games Workshop's own publications, such as Warhammer Community, White Dwarf, and the faction Codexes. The latter two were the de facto publications to find show-quality miniatures, and also published glamour shots of Golden Daemon minis (which were ostensibly the best-painted minis in the world!); while the former presently publishes content curated from Instagram.
