I don't think that watching TV is the second best way to learn, of course, everyone learns differently. Other than communicating directly with others, reading is the second best way to learn for me. Reading affords you the time to examine new vocabulary in a way that just watching TV won't.
If you prefer watching TV, my suggestion would be to find a show that really interests you. You will be motivated to understand it if you find the subject matter compelling. If you can get closed captioned
for hearing impaired subtitles in Spanish for your favorite Spanish-language
show, it can be very helpful. Hearing what people say and seeing it written in Spanish can be very educational.
If you are not currently motivated by watching telenovelas, and Sabado
Gigante
, I would suggest the magazine-like pseudo news shows like
Primer Impacto. The Spanish used is often easy, and you wont get tangled up in lots of words.
