commercial network television series devoted to the arts. Cooke

1. This phrase describes a type of program Cooke was involved with.

2. The blank likely needs a word to complete the description of the series.

3. "Omnibus" is a known series, so the blank might be "was" or similar, but the sentence structure suggests a noun or adjective describing the series. Given the options, "genre" or "type" could fit, but the sentence is incomplete.
