Help me, please
Student or Learner
Here is the sentence:
1)Television has (proven)an important source of production finance.
The correct answer is proved and I chose it, but I would like to know why "to be" is not used in this case.
A) Is it the Nominative with the Infinitive=Complex Subject?
It is a pity that in all my grammar books different authors write something like this
"The linking verbs, appear, prove, and seem are sometimes followed by the infinitive to be and a complement (an adjective or noun). This use of the infinitive is called a predicate infinitive (PI)."
I always don't like these "often" or "sometimes".
Could you look for an example of using prove like in my sentence without to in a good grammar book.
It's very important for me, but I can't find any example of using prove without to in grammar books.
Thanks in advance!

Television has proven(US)/proved(BrE) an important source of production finance.
has proven/proved = linking verb
an important source of production finance = predicate nominative (NP)
Television has proven/proved to be an important source of production finance.
has proven/proved = V
to be an important source of production finance = Od
to be = linking verb
an important source of prod. fin. = pred. nom.
Thanks a lot!
The point is that I can't find any examples of using "prove" without to be in goog grammar books)
