Compaq Computer Corp., Microsoft Corp. and Tandy Corp. have agreed to a three-year deal to sell Compaq PCs with pre-installed MSN software through Tandy’s RadioShack chain. Consumers who purchase the Compaq Presario Creative Learning Series will be able to access a tri-branded portal site that lets them sign up for Net access from either MSN or Compaq.Net powered by MSN. -– Margaret Kane, ZDNet News
