A system and method for delivering advertising (100) to a user is disclosed. Values for characteristic properties of advertisements and stored media content items are determined (201, 203). A comparison is made between the characteristic values of the advertisements and the stored media content items (205). An advertisement is selected for delivery to the user according to the comparison (207). Individual advertisements and media content items may be compared across some or all characteristics (301), or individual advertisements may be compared to all the media content items for individual characteristics (401). Key characteristics may be identified for which the stored media content items exhibit a strong commonality (500), and comparisons made for only those key characteristics. A Lambda virtual' media content item may be created (603), with characteristic values representative of the stored media content items, and advertisements compared to that Lambda virtual' media content item (605).
