The FTC is reportedly looking into the way handles companies that build applications and services for its microblogging platform, according to Business Insider.

Neither the FTC nor Twitter would verify an investigation or comment in any way on the situation.

Dan Olds, an analyst with The Gabriel Consulting Group, said he's not surprised that the FTC would turn its attention to Twitter, since it's a growing, high-profile company.

"Young and fast-growing companies thrive on attention, except when it's from the FTC," he said. "But when that young company controls a whole category of applications and has made some moves to deny others the chance to live in their ecosystem, it's bound to get some scrutiny sooner or later. Looks like it's sooner in Twitter's case."

Olds added that there's a fine line between serving users better and denying potential competitors a piece of the pie. And, if there is an FTC probe underway, that may be the line the government is looking at.
