How did the NYSE answer the NASDAQ's head start in electronic trading?

1. The NYSE fell behind its more nimble rival, which already had an electronic platform. 2. It answered by going public and merging with Archipelago, a major electronic communications network, to enter the electronic marketplace. 3. The NASDAQ responded immediately by acquiring another such network, Instinet's INET. 4. The NYSE then signed an agreement to merge with Euronext, creating the first exchange to span the Atlantic. 5. It was the NASDAQ, not the NYSE, that increased its ownership of shares in the London Stock Exchange to 25 percent. _Source: OpenStax Introduction to Business (CC BY 4.0), Ch 16 "Understanding Financial Management and Securities Markets", section 16.8 Trends in Financial Management and Securities Markets_
