Regulators from the European Union are getting involved in the Federal Trade Commission investigation of Apple's business strategies that was opened up in June, according to a New York Post report on Tuesday.
The inclusion of the EU regulators means the investigation could now stretch "another four to six months" before the FTC reaches any official conclusions, according to the Post's sources.
The focus of the probe, which remains unconfirmed by the FTC, centers on Apple's App Store developer agreement. In early April, Apple adjusted its wording in a way that outright barred developers from using third-party development tools such as Adobe's Flash Compiler, or in-game engines like Unity 3D.
