I have to say I do like Harry Smith...
CBS has never had any success with a morning show ever, at least not since the days of doing hard news in the morning. From that ridiculous thing with Bob Saget and Mariette Hartley to Phyllis George's terrible journalism, it caused the show much disgrace. The likeable attempts of Swayer&Kuralt, Maria Shriver's stint and Smith&Zahn all failed miserably, and of course the Bryant Gumbel stunt failed too.
The only time CBS This Morning ever got a leg up was when it passed GMA in the ratings when GMA was suffering through the Lisa McRee/Kevin Newman period, even at a time when many, many of the stations were pre-empting the first hour of it. Even we did that one, and I also know CBS O&O KCNC did as well!
However, once the Early Show launched, most of the stations that were pre-empting This Morning's first hour carried both hours of The Early Show at CBS' demand. But of course some never complied and some have started pre-empting again, at a time when networks are more aggressive than ever in curbing pre-emptions.
