Hiii
This is what its said in Wiki
"Over the next 20 years, SIN would acquire other top-rated Spanish-language television stations throughout the United States; as part of its expansion, the network acquired additional stations, WLTV in Miami and KTVW in Phoenix; and reached a part-time affiliation with WCIU-TV in Chicago."
So it became one of the top-rates Spanish-language TV stations when it was expanding throughout the US (or however you want to write it)
Hope it helps!
