A few aspects of weddings have been disrupted: - Registries: the article itself talks about Zola, for example. Although traditional registry sites (e.g. bloomingdales, bed bath and beyond) seem to still have most of the market in my experience. - Invitations: You can still go to someone local for this, especially if you need something customized, but more and more people are creating their invitations online. But there are a bunch of pieces of the wedding that are stubborn to change. Other major expenses include venue, catering, photography, flowers and music/entertainment. But finding these things, which often involves driving out and meeting with someone face-to-face, or at least talking to them over the phone, is part of the process that people love about weddings. Companies spend $30,000 on events. But most people spend $30,000 (or whatever your wedding costs) are paying for the experience of planning the party. My wife insisted on driving out to sample caterers' food (which for me was the best part of wedding planning) and meeting the potential photographers in person. If this was strictly a business transaction, then yes, an app could probably make this more convenient. But the process is part of the experience that people seem to like. EDIT: A lot of people don't see the rationality in having a big, expensive wedding that takes a long time to plan. My brother had close friends and family at a restaurant and it was great. If more people did that, then the wedding industry would be "disrupted". But I'd venture to guess that most people spending large amounts of money on their weddings enjoy the current aspects of the process.
