As the new fall television programming commences, TiVo Inc. reports that Private Practice and Bionic Woman were the only two premiere shows that penetrated TiVo's Top 50 Season Passes, ranking at #18 and #43 respectively.

TiVo's Season Pass(TM) feature allows subscribers to regularly record their favorite shows each time the program airs regardless of the time, while automatically skipping repeats and without the use of tapes or timers.

"Premiere week's TiVo Season Pass results serve as an indication of early marketing success and buzz generation, as well as the public's overall appetite for these shows," said Todd Juenger, Vice President & General Manager, TiVo Audience Research & Measurement. "Although subscriber behavior habitually begins slowly -- some are slow to add a new show to Season Pass and may sample it for a few weeks before making that commitment -- 'Private Practice' and 'Bionic Woman,' two highly anticipated shows, opened with high expectations from a confident audience."

According to Juenger, these initial rankings are not a harbinger of a program's ultimate success and noted that last year, the highest ranked new program on the Season Pass list was Studio 60 until it was overtaken mid-season by Heroes (which went on to crack the Top 10 and currently sits at #6).
