B
|
Base |
The survey universe, sub-universe or primary target group on which a piece of computer analysis is based – e.g. all respondents. The readership and buying habits of this group can then be examined. The unweighted base is another word for unweighted sample and is the actual number of respondents. |

Bleed |
When the print area of an advertisement extends to the edge of the page rather than being set in a box or having a white border.

|
Cumulative Readership |
The net reach achieved by a number of insertions of an advertisement in a single title or schedule. This is the number of people who have at least one opportunity to see (OTS) an advertisement.
