For many years this was enough to make the company's stock price rise, as companies were often valued largely on their return on investment. The aggressive nature of the conglomerators themselves was enough to make many investors, who saw a "powerful" and seemingly unstoppable force in business, buy their stock. High stock prices allowed them to raise more loans, based on the value of their stock, and thereby buy even more companies. This led to a chain reaction, which allowed them to grow very rapidly.
The Conglomerate has had three incarnations, the first led by Booster Gold, and including Praxis, Maxi-Man, Echo, Vapor (Carole Donahue), Reverb (Vibe's brother), and Gypsy. This team initially is hostile towards the JLI (Booster had recently quit the group over his perceived lack of respect from his peers), but the two groups gradually become more friendly. Eventually, the members of this version of the Conglomerate drift away. Booster Gold parts ways with the team during an attack upon New York by Despero. Claire does not want the team to go, as they will only get in the way. Gold, who figures he has enough experience with the League, leaves on his own.
