Stations offer different kinds of ad time. While the specific labels vary from station to station, generally there is "preemptible" and "non-preemptible" ad time.
Preemptible ad time can be snatched away by a higher bidder, while non-preemptible time cannot. Because of that, non-preemptible ad time is more expensive because it virtually guarantees an ad will run.
There's also a middle way, known as "preemptible with notice," which gives campaigns a chance to match a new offer from another ad buyer before the campaigns lose the time slot for their ads to a higher bidder.
Neither Republican Supreme Court candidate is known to have bought ad time, something that could make it more expensive for them to get on the air when they do.
There are two 12-year terms on the ballot this year.
Republican court candidate Allen Loughry has about $400,000 from a public financing experiment that the state Supreme Court last week partially struck down.
He gets to keep that money and is now free to raise more from private donors, although he will not receive more public financing money. He's said to have already filmed a commercial. That means he could have a noticeable ad presence depending on his approach to the fall.
Judge John Yoder is the other Republican candidate. He reported having less than $8,000 on hand in his last campaign finance report - hardly enough to have a noticeable ad presence.
Both Chafin and Davis have personal wealth they can use to finance their campaigns.
In the 3rd Congressional District, incumbent Rep. Nick Rahall, D-W.Va., is on air, as is his Republican challenger, Delegate Rick Snuffer, R-Raleigh.
There's also a new ad from the National Republican Campaign Committee, or NRCC, which spends money across the country to try to elect Republicans to the U.S. House.
The NRCC has spent $167,000 so far this month on media buys to oppose Rahall and $22,000 on polling, according to federal campaign finance records. Its ad attacks Rahall, saying he has forgotten about West Virginia.
Democratic Party executive director Derek Scarbro pushed back against the ad in an email to reporters by highlighting votes the party considers in West Virginia's interests.
Snuffer's own ad is set to upbeat music and portrays him as a carpenter in an unfinished house.
"I'll take a hammer to President Obama's agenda," Snuffer says in the ad.
Rahall's ad was not yet online Monday afternoon. His campaign last week said it would not air ads today in honor of the terrorist attacks of 11 years ago.
Scarbro said Republicans were using the same lines of attack that have failed them in the past - lines of attack that Tomblin, Rahall and Manchin all have overcome.
The attacks are "not only the same line of attacks but it's the same candidates in many cases making the same arguments against our people that the voters just aren't buying," Scarbro said.
That's a reference to Raese, who lost to U.S. Sen. Joe Manchin in 2010, and Maloney, who lost to Tomblin in 2011.
Republican Party Chairman Conrad Lucas said the Republicans have the resources to get their messages across to voters.
"It's an exciting time for us, and it's very encouraging that our candidates have been able to garner support to promote their message," Lucas said.
Maloney and Raese largely self-financed previous campaigns. It's not clear to what extent they may be doing that again this year.
It's not always easy to tell who is spending how much. That's because some records are not online, not immediately available or never made public.
Some expenditures have to be posted online quickly, like the NRCC's spending. Some expenditures are not made public until campaigns file regular finance reports, which is not very often for state candidates in West Virginia.
Other spending, like that of the pro-McGraw group, is not made public. That's because the ads may be considered "issue ads" and not directly related to Election Day.
TV stations have to keep records on candidates' political spending. But most of that data in smaller media markets is not yet posted online. So getting that information can require trips to stations across the state - or even to stations in bordering states - to figure out how much is being spent.
There have also been radio ads and print ads this year. Maloney released a new radio ad targeting southern West Virginia voters on Monday. A group backed by the Democratic Governors Association has done radio on behalf of Tomblin.
Asked if the Republican Governors Association planned to begin spending in the state soon, a spokesman did not detail the group's plans.
Raese has been running print ads for months, including a new one this week.
