tescopolyEtymologyBlend of Tesco + monopoly, coined in the 1990s.nounThe dominance of the British supermarket chain Tesco.“One cannot honestly revive the old charge of “Tescopoly” because the discounters are still big enough to keep the leader honest; in any case, £3bn-ish of operating profit equals a 4.3% margin on likely revenues of £70bn this year, which is not excessive versus the high-teens returns at the likes of Unilever and Procter & Gamble.”
