I would say don't try to read more into it than there is. Letterman makes fun of someone or something every night with his Top Ten List. Perhaps they used QTN as an example because they exist, and LOGO doesn't. ? Just a thought.
tradewell…the most logical explanation is…Rubenstein Associates is the PR firm for both Q Television and World Wide Pants (the owners of The David Letterman Show). It seems like it was an influence, connections type move. imo
tradewell...none of us know the answers to your questions but when I listened to Dave Letterman read the information on Q Television there was nothing in the USA ad that said it was debuting this month so he got that info from somewhere...to me it was an intentional information piece on QTN...but that's only my interpretation....
