Here are a few I remember re: confusing networks with local channels.
A few months back, on another board I used to visit somebody posted a rant about 'Fox'. Not Fox News, mind you, the Fox network. He was upset that the 'idiots' at 'Stupid Fox' had 'cancelled Seinfeld'...or, in English, the Fox affiliate that reran that show every night at 7 had removed it from the schedule.
Regarding confusion of channel numbering, in early 2002, when NBC made its affiliate switch in the Bay Area, it went from Channel 4(KRON, never owned by the network) to KNTV (channel 11, formerly an ABC affiliate, which NBC purchased in order to make the switch). Although KNTV remained on OTA channel 11, it was assigned channel 3 on Bay Area cable systems (mostly Comcast).
Thus, KNTV rebranded itself as 'KNTV 11, NBC 3', downplaying its analog channel number. KNTV had been located in San Jose, but with the affiliation change, it was added to systems in the North and East Bay Area, where it had previously
At the time, TV GUIDE was still publishing local listings, and the San Francisco edition carried the Sacramento channels..among them, KCRA, that city's NBC affiliate...on channel 3.
There was confusion among viewers in the East Bay(Oakland) area, who had recieved KCRA on cable, and were confused by now, in efefct, having two 'Channel 3's' showing NBC. Eventually, KNTV stopped saying the number '3' on-air, and started using 'NBC 11'(shortly before this year's digital transition, they stopped using channel numbers altogether, and are now 'NBC Bay Area'.)
Finally, a childhood memory: at some point when I was in 3rd grade in 1982, some of my classmates must have gotten confused about the syndicated reruns of 'Happy Days', while the show was still in first-run(post-Ron Howard) on ABC. I remember a discussion of how 'Richie is on the show on channel 44'-KBHK, the independent channel showing 'Happy Days Again', as the reruns were titled-'but he's in the Army on Channel 7'-KGO, the ABC affiliate. One kid seemed to get that 'Richie' was the character's name, but was convinced Ron Howard was somehow 'still there, they just don't show him'.
