A conventional contents-watching device, etc. calculate users' tastes of contents only on the basis of watching frequencies, so that variety programs that the users are less interested in but that are broadcasted every week are apt to get a higher degree of users' tastes than a soccer game of the Japanese national team that the users are highly interested in but that is broadcasted only several times per year. In order to solve the problem set forth above, the present invention proposes a contents-watching device that calculates a taste value by normalizing a watching index indicative of the number of contents-watching times or the like for every contents-attribute with an emergent index indicative of the number of contents-watching chances, acquires an contents-attribute connected with contents to be a subject for watching recommendation, and has a function to calculate watching recommendation information by using the taste value of the contents-attribute.
