5. Oracle and Sun

A software giant joins forces with a hardware giant; the results are expected to shake the world, right? Unfortunately this cannot be said of the union between Oracle and Sun. In 2009, Sun the software company was taken over by the hardware giant’s Oracle to save the later from a bad phase.

As a result thousands lost their jobs and the projects being developed by Sun were killed. Ultimately Sun’s core software business continued to decline steadily. Oracle was trying to cover its losses and thus filed lawsuits against Google. The trial is still on and has a substantial amount in question. If Oracle is given the damages they will recover the losses but otherwise it will end up being one of the worst mergers ever in the history of the world.
