In hopes that some producer might think of using fictional products from other shows (and thus help create new links between shows), here are some recent items I've culled from various TV series in the last few weeks:
Pan Transit Airlines - went out of business back in the sixties
'THE BOOK OF DANIEL'
St. Barnabas Church
Newbury, New Jersey
Devlin-McGregor - a pharmaceutical company
[This is the same company that was ultimately was responsible for the death of Dr. Kimble's wife in the movie version of 'The Fugitive'.]
Cedar Hills Sanitarium
"Thicker Than Water" - movie based on the Crumbs' life
"Lesbian Prison Stories" - a paperback book
KXRY - San Francisco classical radio station
According to an anonymous poster at the Mind of Tommy Westphall Live Journal, Morley's Cigarettes were seen in two episodes. This links the show to several other TV shows, most notably 'The X-Files' and 'Buffy The Vampire Slayer'.
The Recovery Channel, a cable tv network
'The Long Haul''
And if you find anything of trivial interest in the shows you watch, let me know. I can't catch everything and can always use the help!
