Yes, you have correctly identified the linking verbs in each of the sentences. A linking verb is a verb that connects the subject of a sentence with a noun, pronoun, or adjective that renames or describes it. In these sentences, the linking verbs are used to link the subject of the sentence with a complement that describes or renames it.

1. "I am fond of both kinds of comics." - The linking verb here is "am." It connects the subject "I" with the adjective "fond."

2. "Joseph Pulitzer was the first to publish color funnies." - The linking verb here is "was." It connects the subject "Joseph Pulitzer" with the noun phrase "the first to publish color funnies."

3. "The sales of his newspaper were high." - The linking verb here is "were." It connects the subject "sales" with the adjective "high."

4. "Sunday Funnies soon became part of his papers too." - The linking verb here is "became." It connects the subject "Sunday Funnies" with the noun phrase "part of his papers."

5. "Now comics have become serious business for publishers." - The linking verb here is "have become." It connects the subject "comics" with the noun phrase "serious business for publishers."

To identify linking verbs in a sentence, you can ask yourself if the verb is connecting the subject of the sentence with a noun, pronoun, or adjective that describes or renames it. If so, it is likely a linking verb.
