The telenovelas are broadcast in high definition where available – and in letterbox format on standard definition broadcasts. During the all-novela period, MyNetworkTV promoted itself as "the first all HDTV network." In addition, early shows carried a SAP signal carrying a Spanish audio track, but an alternate closed captioning channel with Spanish translation was not used; in execution as most affiliates of the network never utilized SAP channels due to a lack of programming requiring it, and outside of major markets, the Spanish dub was never heard.
