In this paper we analyze the most discussed television programs broadcast in Spain based on the number of users in Twitter (not comments).There were two objectives: to know which television programs are the most tweeted based on their genre and their time slots, and to observe if the most watched television programs are also the most tweeted.We use a quantitative methodology based on Spearman's correlation and the Kappa coefficient from the data obtained during 30 days (150 observations).The data allows us to conclude that the most tweeted programs are tabloid talk shows and TV news magazines, reality shows and sporting events, and that 63.3% of the most tweeted programs are broadcast between 8:30 p.m. and 12 a.m.
