U.S. Antitrust Officials Investigating Broadcom's Semiconductor Products

U.S. antitrust officials investigating Broadcom Inc. are significantly broadening their scrutiny to focus on whether the chipmaker abused its dominance to sell some of its most important semiconductor products, according to documents and a person familiar with the probe. The Federal Trade Commission is seeking evidence that Broadcom’s conduct harmed competition in Wi-Fi and switch-chip markets, according to a civil investigative demand issued last week and obtained by Bloomberg News.
