Exactly the opposite of this happened. Almost all content on the early-mid 90s web was user-generated. The bulk of it was personal "homepages" with low production values describing hobbies or technical interests.

Very few large corporations had even heard of this crazy new "Internet" thing in the 90s, and even fewer cared. Almost none had a corporate webpage even listing their address and phone number, much less produced any content at all.

Many had the .com domain name corresponding to their corporate brand registered by domain squatters they later had to buy it from. Some didn't even notice for years.
