New York—Canon Communications, a b-to-b media company, has sold the assets of Micro, including its circulation list, to b-to-b media company PennWell Corp. and shuttered CE. Micro, which runs six times a year, covers advanced process and equipment control, defect reduction and yield-enhancement strategies for the semiconductor and related advanced microelectronics manufacturing industries. CE, which covered regulatory compliance for electronics engineers and was published bi-annually, “was a tiny little product, and with the consolidation of suppliers and manufacturers in that space the role of advertising went to nothing,” said a person familiar with the situation. Both titles had a circulation of less than 25,000, according to this person. Canon is owned by b-to-b media holding company Apprise Media, which is bankrolled by private equity firm Spectrum Equity Investors. PennWell Corp., whose flagship title is Oil & Gas Journal, targets several industrial markets with about 45 trade titles.
