Is Channel just the name for the same thing in v2?

Yes.

ExpressionEngine 1.x — and its former code base pMachine Pro — naïvely distinguished a collection of data stored in the database as a "weblog".

This nomenclature was used widely throughout the Control Panel and naming of Modules, right down to the the Weblog Entries Tag used in templates.

ExpressionEngine 1.x Weblog Entries Tag:

{exp:weblog:entries weblog="portfolio"}
    <p>{title}</p>
{/exp:weblog:entries}

As the publishing needs of web sites evolved and ExpressionEngine itself matured, EllisLab recognized that calling everything a "weblog" was silly (to put it into my own words) and didn't reflect real world use.

So with the release of ExpressionEngine 2.x Public Beta in December 2009, weblogs were officially renamed to channels, starting with EE 2.0, Build 20091202.

Using the code snippet above, you'll see the usage of weblogs was renamed to channels:

ExpressionEngine 2.x Channel Entries Tag:

{exp:channel:entries channel="portfolio"}
    <p>{title}</p>
{/exp:channel:entries}

This change in nomenclature positions ExpressionEngine from being viewed as simply a Blogging Tool into a more robust Publishing Platform or CMS (Content Management System).
