KBTR-CD
KBTR-CD channel 41, known on-air as WBTR 41, is a television station in Baton Rouge, Louisiana affiliated with This TV. The station is owned by Louisiana Television Broadcasting, the owners of area ABC affiliate WBRZ-TV. The station is seen on Cox Communications and AT&T U-verse. Its transmitter is based on the property of WBRZ-TV, where its studios are also co-located, just south of downtown.
While the station is licensed as KBTR-CD, it brands itself on the air as "WBTR 41" to help fit in with other stations in the market. To keep other stations from using the WBTR calls (other than in legal IDs), KBTR has registered "WBTR" as a Registered trademark.
