When it comes to market research outfits, the maxim has to be you pays your money and you takes your choice, which is why Computergram doesn’t devote much space to their reports: while Storeboard Inc was saying that Compaq Computer was top of the tree in US dealer sales for the April to June quarter (CI No 989), IMS America National Computer Retail Reports was saying that in the three months ending April 1989, Apple Computer and IBM were tied for dollar volume of sales through computer stores, and that it was the first time IBM had fallen below 20%, as well as the first time Apple had drawn level or exceeded IBM sales in a non-Christmas quarter.
