Give me original and cohesive commentary on this using a critical straitforward informal tone: K-Pop became pretty much a Big 4 featuring M-net, In the current era of K-pop, it is widely acknowledged that we are experiencing a remarkable golden age in terms of both the quantity and diversity of immensely successful musical groups, However, it should be noted that a significant majority of these groups hail from Hybe labels, M-net's survival shows, or belong to the lineup of The Big 3, and Unless YG Entertainment continues to make dumb decisions and undergoes a decline in reputation, it appears highly likely that this prevailing trend will persist, Kpop is very oversaturated, It seems that "The Big 4" companies are consistently introducing and planning to debut new groups at an unprecedented frequency, This trend ultimately leads to these companies securing a larger portion of the overall market share, primarily due to their substantial resources and influence, Undoubtedly, K-Pop has been experiencing exponential growth, but I believe we may have reached a saturation point in terms of the overall popularity and interest in the genre as a whole, In fact, I would argue that the peak of K-Pop's popularity was more prevalent during the years 2018 to 2020, Presently, we are witnessing the emergence of colossal fandoms that predominantly support groups affiliated with the Big 4 companies or those who have gained prominence through M-net shows, accounting for approximately 95% of the fandom's attention, Basically, there has been a noticeable trend of large companies in the industry gaining more dominance over their smaller counterparts, I can recall a time when Cube or Woollim were considered major players in the K-Pop scene, but now it seems that the majority of what is commonly referred to as "mid-tier companies" are facing significant challenges and often rely heavily on just one musical group for success, In the past, it was much easier for these companies and their groups to garner attention, as if you were a fan of K-Pop and listened to the top 20 most popular groups, you would likely find that half of them belonged to mid-tier companies, However, in today's landscape, with the rise of monster companies like Hybe and the prevalence of M-net's survival shows, the ratio has drastically shifted, and mid-tier companies have a much smaller chance of being represented in that top 20 list, perhaps only around 5 out of 20 if they're lucky, This means that if you are part of what is typically considered a mid-tier company, it is now more challenging than ever to stand out in the industry, However, on the flip side, it is also slightly easier to amass a decent following due to the sheer size of the K-Pop fanbase, In recent times, I have observed a noticeable gap, particularly among girl groups in the K-Pop industry, With the exception of IVE from Starship Entertainment, who already had high anticipation due to their association with eyes one, and StayC benefiting from the popularity of its producers, there seem to be few recent girl groups from non-major K-Pop companies that have achieved significant success, The truth is, in order to make a mark, you either require a substantial investment like what LOONA received or must be extremely fortunate to have a breakthrough hit, However, even if you do manage to achieve success, it is often fleeting, with people quickly moving on and not readily purchasing your merchandise, Consequently, becoming a solid and successful group solely through smart strategic decisions or by carving out a niche sound is becoming increasingly challenging, so What is your opinion on the future of K-Pop? Do you believe it will predominantly be dominated by the Big 4 companies and M-net? Or do you think there will still be opportunities for smaller companies to thrive as long as K-Pop remains popular?
