Which syllable is primarily stressed in the word "television"?

I was taught to stress the first syllable of "television", but some dictionaries stress the syllable before -sion. My other question is "Does stressing VI before -sion exist in AmE?

Solution 1:

Merriam-Webster says that putting the primary stress (or accent) on the second-to-last syllable of television is an "especially British" pronunciation.

I'm an American English speaker, and I don't remember ever hearing that pronunciation.

In American English, the pronunciation with primary stress on the first syllable may be analyzed as having tertiary stress on the second-to-last syllable: ˈteleˌvision.
