de braco -i see you edited your most popular in the world statement, i'm pretty sure that honorific belongs to tkd anyway. So good on you, triple stealth edit. make no mistake, bjj will overtake judo on a worlwide scale in time, and trips will slowly circle the drain of history
Actually your wrong, judo is in fact the most popular martial art in the world. I edited my post because he was talking about the US, so I wanted to give him a detailed answer that focused more on what he was actually talking about.
BJJ is not going to get anywhere close to overtaking judo in our life time for a variety of reasons:
1. There is an IOC recognized combat sport named Jujitsu. It's pretty cool kind of like a mix of kickboxing and judo, mostly practiced in Europe. They aren't going to recognize another one with a similar name.
2. Outside of Brazil and the US, no other countries are consistently producing top players. It is also not popular in many countries where judo is.
3. The IBJJF is a for profit organization that only holds it's most prestigious events in America because we can afford to pay their fees.
4. Jiu jitsu is not exactly unified and working towards a common goal and many people despise the IBJJF, but participate because winning there gives them arguably the most prestigious titles in the sport. No Gi, Sub Only, Pro shows, etc. will continue to grow in popularity.
5. The style of submission grappling that probably has the best chance of getting into the Olympics due to some things happening behind the scenes and the fact that it has athletes representing more countries than jiu-jitsu is Grappling which is run by UWW and a little different than most typical Jiu-Jitsu rule sets. There are many different restart positions on the ground if the action goes out of bounds for example and your opponent gets takedown points if you pull guard without an immediate attack, among other things.
6. Jiu-Jitsu is fun to practice, but boring to watch and very difficult to understand for the average person.
It is pretty obvious that you don't actually watch judo if you think "trips" are overly dominate now. Plenty of people win with Uchi Mata, Seoi Nage and other classic throws that don't involve "tripping" your opponent with your legs. All you have to do is go on IJF's YouTube channel and watch highlight videos of ippons from a recent tournament.
