FIELD: physics, computer engineering.

SUBSTANCE: invention relates to recommendation of a product or service to a user. The system comprises: a first extractor (S200) for applying a first feature extraction algorithm to extract first features characterising content of a data input processed by a first application running on the system, wherein said first extractor (S200) is adapted to detect whether said content of said data input relates to a television program or an existing film or television production; a switching functionality triggered by content items in the data input processed by the first application so as to activate the second application, wherein said content items relate to said television program or existing film or television production; a second extractor (S100) for applying a second feature extraction algorithm to extract second features characterising content of a database (32) of a second running on the system; and a comparator (S300) for comparing the first and second features to identify matching items used for the recommendation.
