OTTAWA — Ever since the introduction of its first BlackBerry more than a decade ago, Research in Motion has defied expectations that it would be gobbled up by a larger rival and has effectively created the market for smartphones.
But as Google moves to buy Motorola Mobility, RIM, already under pressure from diminished prospects and declining market share, is once again the subject of takeover talk.
Since the Motorola acquisition was announced on Monday, shares of RIM, which have suffered for much of the year, have shot up more than 10 percent, mainly on speculation of a sale.
