Generational differences will continue to impact this transition to new media consumption. Those generations fluent in both the worlds of new and old media will continue to use traditional formats while increasingly sampling new ones. Those aged 30 to 34 are perhaps the most prolific in their use in both old and new formats, leading other groups in the size of their DVD collections (53% have over 40 DVDs), the likelihood they use a DVR (43% own one), and whether they purchase music online (24%), ABI Research found.
