I hear everything is on track for the Action News family to be moving into their new digs in the next 4-6 weeks. Construction, which began in the summer of 2007, was completed some time ago. Now, it's the completion of all the wiring involved of an HD state-of-the-art type facility it is.
I'm told the station should go on-air from the new building by early September. As I wrote in late April, don't expect any drastic changes in the look of "Action News", only some tweaks here and there. The studio will definitely be larger which should allow some elbow room in future programming.
WPVI went on the air September 13th, 1947 as WFIL-TV. WFIL-TV was the home of Dick Clark's "American Bandstand" which hit our airwaves in 1952 and went national on the ABC network in 1957. WFIL-TV was also ABC's first affiliate.
A little known fact I found interesting? According to Wikipedia, channel 6 never carried ABC's new morning news show, "AM America", back in 1975 when ABC decided to create a morning news show to compete with NBC's "Today". ABC cancelled the ratings struggled "AM America" six months later and debuted "Good Morning America" in October of that year. WPVI only aired the first hour, opting instead, to air locally produced "Captain Noah and his Magical Ark" in the 8 a.m. to 9 a.m. hour. It took three years until ABC pursuaded WPVI to air the show in its entirety. Similiar situations happened with ABC's "Home" show (anchored by Robb Weller and Sandy Hill) and daytime soap, "The Edge of Night". "Home" was preempted entirely and finally hit WPVI's air only to have the first half hour preempted. "The Edge of Night" never aired on WPVI but instead, on independent stations in Philadelphia that were contracted by ABC to carry the show.
