The Monday night debut of Conan O’Brien’s new talk show on TBS drew 4.2 million viewers, making it the highest-rated late night show of the evening on broadcast television or cable, Deadline.com reported Tuesday.

The first episode of “Conan” beat its direct competition on cable -- Comedy Central’s “The Daily Show” and “The Colbert Report,” which drew 1.3 million viewers and 1 million viewers, respectively -- and on network TV, with “The Tonight Show” bringing in 3.5 million viewers and “The Late Show with David Letterman” drawing 3.4 million.

The episode also ranked as the top late-night talk show broadcast on basic cable of all time.

“Conan” debuted to mixed reviews, with Entertainment Weekly finding its opening night “familiar and a little tired” and The Wall Street Journal’s Speakeasy blog declaring it “same old same.”

The comedian’s new show comes after a nine-month absence from television after he was replaced as host of NBC’s “The Tonight Show” by previous host Jay Leno after just eight months on the job.
