Aside from the first season of The Wild Wild West, Paramount hasn't done a whole of lot special features for their old TV on DVD. Of course, the picture and audio on these (including The Fugitive) is so good, it's hard to complain, but...
For some more examples of some great extras onold TV, check out Time-Life's Get Smart set with a TON of bonus material, both archival and current. Also, the "Definitive Editions" of the original Twilight Zone had a bunch of stuff, including commercials from the period.
Oh, and The Fugitive on DVD is fantastic. My favorites from the first 15 are "Fear in a Desert City," "Ticket to Alaska" and "Girl from Little Egypt." I hope Volume 1 sold well enough so more volumes roll out in the next few months.
