I just don't really think competitive pinball lends itself to video. I play probably around 8-12 hours a week on location, so it's not for lack of love of the game itself. Even at Pinburgh or another major event with screens in place at the venue, I watch the finals for a few minutes, and then get bored and wander off to grab a machine. This applies even with close friends being on stream.
I find a lot of value in Bowen tutorials and I've probably watched 20 odd hours of those. I'm not sure I've watched two full hours of live or recorded competetive play. I know a few players that love watching streams, but I would say that they are a minority.
Pinball has the issue of being uniquely state based. It would help if manufacturers would introduce a live out put of relevant game state information specific to the game being played that could be automatically Incorporated into the feed. Locks, modes completed, score, etc. Sort of like how the NFL shows time outs, possession, yards to first down on screen at all times. This might help people understand what's actually going on during play a little better. Slower games with less state based information generally are easier to follow, but that's certainly not the direction pinball is going nor should it.
While I didn't watch it, the Head To Head event recently corrected for a number of the issues with the sheer complexity of pinball rules. One stated goal and both players often employing the same strategy to get there, under race-like conditions.
I think the videos Karl (I think) produced for the Head To Head event were absolutely wonderful and helped those less familiar with a specific objective understand what the players were attempting to do. I didn't actually know when a few of those events triggered myself.
While I would love to see pinball on ESPN someday, I think our hobby may be a little too niche for broad spectrum appeal, largely because of the sheer complexity of it that likely appealed to many of us in the first place. I fear we may be less darts, pool, and bowling and more Settlers Of Catan and Magic The Gathering.
If growing the player base is the ultimate objective, I think inexpensive local tournament play friendly to beginners, league play, and hands on, one on one or small group tutoring is a more effective path forward than streaming video of high level events. That's what seems to have worked best for Seattle and Portland at least.
