I made my TV appearance for the first time by appearing on a Nationwide TV quiz show at the age of 6 (three more TV Quiz show appearances since then), but it's definitely not because of my hobby!
I got two interviews on Korean Hobby magazine (they were Sister-and-Brother kind of magazines, actually, so, no big deal) for my Phonograph/record collecting when I was 15 years old, and later, I also appeared on two Movie magazines. They were mostly concentrated on my blog (now closed) specialized in history and antiques; 78s and old films.
On the other hand, one of my phonographs - The Japanese Victor Victrola J1-50 - was featured several times on TV documentary episodes and a movie as well.
There is a rare Columbia record which contains a speech of Sohn Kee-Chung, the Korean Winner of 1936 Berlin Olympics Marathon (more info about him here;
http://en.wikipedia.org/wiki/Sohn_Kee-chung), and One of the big producer at that TV documentary series got a copy of that record in a flea market. He thought that it was a major discovery (which is actually not - it is definitely a scarce one, but I myself have it, and I know at least 10 people who has it), so the Network decided to show about the along with the segments about the exhibition on Sohn's life which was conveniently going on at that time.
The Network, of course, have some modern equipments for playing 78s, but they didn't have any 'Contemporary machines from that time' to play that record 'more properly', and somehow, the producer contacted me from my YouTube channel, as I uploaded a video about Sohn, and also some couple of videos with Phonographs on my channel around that time. They wanted to borrow the phonograph from me, and I made it shipped to the TV station. It played the record, and also the second side which contains a song about Sohn. I gave the operating instructions for them since none of the people involved on that , but I forgot to mention about changing the needles after each playing! As a result, the final passages of second side sounded really, really awful.
After the episode was over, they gave a small credit for me. That's how my Phonograph (not me!) got the first TV screen debut. And after that, the Documentary team borrowed this machine for about 5 more times whenever they need a scene for a phonograph playing certain 78rpm record. I got tired of lending this machine to anybody else after a record I gave them to play got cracked when came back to me, so I told them to find some others for their needs. And now they are using those Indian crapophones with
LPs, obviously a prop in their basement!
After that, I made this phonograph appeared on a comedy film, set in a Korean radio station of the 1930s. I gave them a Backhaus record for playing, but in the movie they dubbed a Glenn Miller on that segment - what a transformation!
