Tech giant Apple Inc's board of directors is reportedly concerned over the alleged lack of innovation under CEO Tim Cook's leadership.

The Cupertino, California-based company has failed to introduce any new revolutionary products since 2012. The company's laptop lineup got a refresh several months back.

Some of its members of the board, including Disney chief Robert Iger, Intuit chairman Bill Campbell, J Crew's Millard Drexler and former US vice president Al Gore, are reportedly not pleased with the sluggish pace of innovation at the company.

Citing sources, Fox Business reported that the board members wanted Mr. Cook to introduce some industry-leading smartphone, tablet or other hardware.

In a televised report, a Fox Business correspondent said, "What have they had lately? They have had the iPad, they've had a few other things, but they don't have anything innovating from what came from Steve Jobs."

The correspondent said that the lack of an innovative product was increasingly putting pressure on Mr. Cook to innovate. However, the the correspondent added that Mr. Cook's job is not in danger yet.

It may be noted here that many of the products rolled out by Apple during 2012 were developed under the purview of late Steve Jobs, who passed away in October 2011.
