41It is settled case-law that, although the importance of market shares may vary from one market to another, the view may legitimately be taken that very large market shares are in themselves, save in exceptional circumstances, evidence of the existence of a dominant position (see, in relation to abuse of a dominant position, Case 85/76 Hoffmann-La Roche v Commission [1979] ECR 461, paragraph 41, and, in relation to the previous merger regulation, Case T-102/96 Gencor v Commission [1999] ECR II-753, paragraph 205, and Case T-221/95 Endemol v Commission [1999] ECR II-1299, paragraph 134). That may be the situation where there is a market share of 50% or more (see, in relation to abuse of a dominant position, Case C-62/86 AKZO v Commission [1991] ECR I-3359, paragraph 60, and, in relation to the previous merger regulation, Case T-210/01 General Electric v Commission [2005] ECR II-5575, paragraph 115).
