Despite the drubbing Research In Motion (BB 2.72%) has gotten recently as smartphones have robbed the company of nearly every last shred of market share, leaving the once-glorious BlackBerry phone a relic in the minds of most consumers, there is one demographic where the phone still holds a strong share: European teenagers. Its 64% market share of Spanish consumers aged 11-17 contribute strongly to its 22% market share as a whole in Spain (which is higher than even Apple (AAPL 0.53%) can claim in that country), and its 46% in the U.K. and 14% in France for the same demographic are still both dramatically higher than for any demographic in the U.S. Here, Motley Fool research analyst Lyons George tells us how bargain-bin investors can potentially still stand to make gains off these numbers.
