Rca Cable Splitter Is There Such Thing As An RCA Cable Splitter?

Is there such thing as an RCA cable splitter? - rca cable splitter

I know that television is red, yellow, white, and I called an RCA cable. Is there any way to the end of red, white and yellow on one end, then cut to two sets of connectors in red, white and yellow?

[I want my TV on my DVR box and my Nintendo Wii] connect

Thank you:)
