Lazaridis, who founded RIM in 1984, will become vice chairman. Balsillie will continue to sit on the board but not have any operational role.

Chief operating officer Thorsten Heins will replace them on Monday.

Investors have called for a strategy change as the company struggles to compete with Apple and Google.

Lazaridis, speaking after the announcement, said he recognized things needed to change at the company.

Barbara Stymiest, who has been on the board of RIM since 2007, has been made the new chairman, a post that Balsillie and Lazaridis also shared.

Blackberry, which was once extremely popular with users has suffered major setbacks in recent months.

It had its worst service outage in 2011 and has been losing market share to its competitors in the smartphone markets.

Billions of dollars have been wiped from its market value as shares have tumbled 75% and sales have dropped.

One of its latest offering the PlayBook tablet, a reply to Apple's iPad, has not proven as popular as the company had hoped.
