Larry Ellison's company almost acquired Research In Motion, according to a testimony in court. The CEO revealed the fact while testifying in court against Google - but the big-game acquisition was actually considered way back in 2009, when RIM was closer to its peak.
In 2009, RIM's stock hovered between $45 and $90, much lower than its 2008 peak of $140. At $45, it's rock-bottom recession price, RIM had a market cap of roughly $21 billion, and seemed like a huge deal compared to one year prior, when the company was valued at over $80 billion.
Today, however, the company's stock has sunk to just $13 per share, and the company is currently only worth $7 billion. Oracle noted that the reason it didn't buy RIM in 2009 is because it was too expensive.
Larry also pointed to Palm as a potential acquisition. HP ended up buying that company, however.
