Eras
Who was the most powerful artist in a year, who dominated a decade, who held #1 the longest. Every figure is a defined metric summed or maximised over a date range of stored weekly rows — nothing is weighted by opinion.
Billboard Hot 100 and UK Singles Chart combined, weighted · UK Singles Chart data ends Aug 1, 2025 · How it works
Each week an artist's share is the weighted mean of their Power Share across Billboard Hot 100 ×1 and UK Singles Chart ×0.45 (weights ∝ √population, US = 1). The divisor is every chart's weight, so a number one is worth the same share in any era — and a week before every chart exists, or after one's data ends, sums to less than 100.
UK Singles Chart data runs to Aug 1, 2025; later weeks combine the Billboard Hot 100 only, so their shares — and the most recent years' Era Power — are lower than a full week's would be.
