Who watches online video in the uk?  You may have thought that this was the preserve of the younger market..  Not so the demographic shows that the age group 45 plus accounts for 34% of all online viewers.  The data:

• 15-24 19%
• 25-34 17.5%
• 35-44 19.2%
• 45-54 17.1%
• 55 plus 17.4%

This would imply that video marketing on the Internet would work across the full demographic.  Source
