It may seem strange that, nowadays, it keeps resurfacing and bringing new insights to the mathematical community. In this survey we show how a variant of Holder's inequality (although well-known in PDEs) was essentially overlooked in Functional/Complex Analysis and has had a crucial (and in some sense unexpected) influence in very recent advances in different fields of Mathematics. Some of these recent advances have been appearing since 2012 and include the theory of Dirichlet series, the famous Bohr radius problem, certain classical inequalities (such as Bohnenblust-Hille or Hardy-Littlewood), and Mathematical Physics.engjournal articlehttps://projecteuclid.org/euclid.bbms/1503453706https://projecteuclid.org/open access517.98Hölder’s inequalityMinkowki’s inequalityInterpolationBohr radiusQuantum Information TheoryHardy-Littlewood’s inequalityBohnenblust-Hille’s inequalityKhinchine’s inequalityKahane-Salem-Zygmund’s inequalityAbsolutely summing operatorsAnálisis funcional y teoría de operadores
