What's the most suitable tense for this question?
1) How did the television change?
2) How has the television changed?
If I wrote "How has the television been changing", could it be considered grammatically correct, if I would like to refer to its change during the latest times?
The other two sentences are completely wrong?
Sentence number 1 implies the changes have stopped. There is nothing incorrect (aside from "the") in sentence number 2 although television has a long history and maybe you don't want to focus on the move from back and white to colour. Sentence number 3 or bhaisahab's suggestion is the best if you want to focus on recent time.
Thank you very much for your explanation.
And what about sentence 3: How has television been changing?
Is it correct if I want to talk about changes that are coming about recently?
