Operation Prime Time (OPT) was a consortium of American independent television stations to develop prime time programming for independent stations. OPT and its spin-off syndication company, Television Program Enterprises (TPE), were formed by Al Masini. During its existence, OPT was considered the de facto fourth television network. OPT was also called an occasional television network and occasional program alternative.
