 The 15th anniversary was commemorated in an unconventional manner as the network facilitated a series of re-enactments of the seven historic Lincoln-Douglas debates of 1858, which were televised from August to October 1994, and have been rebroadcast from time to time ever since.Five years later, the series "", which won a Peabody Award, served as a year-long observation of C-SPAN's 20th anniversary.In 2004, C-SPAN celebrated its 25th anniversary, by which time the flagship network was viewed in 86 million homes, C-SPAN2 was in 70 million homes and C-SPAN3 was in eight million homes.
