Showing my age here but I bought my first PC in 1994 and promptly installed a modem (can't remember if it was 9.6kbps or 14.4kbps) to get access to Prestel who were providing an internet service along with the other big ISPs, namely AOL, BT, CompuServe, Demon and Pipex. In the next six years I upgraded to 33.6kbps and a whopping 56kbps (the top speed). In October 2000 I got broadband for the first time from Openreach, it was 512kbps with the Alcatel Speedtouch USB ADSL modem. The following year I switched to Telewest's broadband, which was branded Blueyonder, as I'd been a cable customer since 1998 when I subscribed to Cable London. I'm still a cable broadband customer since 2001, now on VIVID350.
In the early days of broadband, 0.5mbps was more than enough for things such as email, Usenet and a bit of browsing with Netscape Navigator (which appeared in 1994) and Internet Explorer (late 1995). Today 50mbps isn't enough for some households with PCs, laptops, tablets, OTT such as Netflix, smart TVs, etc.
