Highly recommend A History of Modern Computing [1]. Starting with the ENIAC in the '40s through the successive generations of computing technology in the 20th century, it gives a fantastic overview of the field's history.

Sadly, now that I look into it, it looks like it's out of print. There are a few copies available on Amazon, so act now!

There's apparently a second edition which goes up through the dot com crash.

I think that the best sections in this book are on the 1950s through the 1970s: the mainframe and minicomputer eras, and the beginnings of the Internet and personal computers. That's all in the first edition.
