- A method for identifying a trend in a viewer history. The method including: generating a viewing history indicating a number of occurrences of at least one feature in content accessed by a viewer; dividing the viewing history into two or more viewing history portions each of which corresponds to a first predetermined time interval; dividing each of the two or more viewing history portions into two or more viewing history sub portions, wherein each of the two or more viewing history sub portions corresponds to a second predetermined time interval; estimating a trend for each of the two or more viewing history sub portions; and estimating a trend for each of the two or more viewing history portions based on the estimated trend for its two or more viewing history sub portions.
